12.	Logx − log x − 1^2 = 2 log( x− 1)
Answer» Answer: I'll solve whatever I SEE here and understand: logx - logx -1^2 = 2 log (X-1) => log x/(x-1) = log (x-1)^2 => x/x-1 = 1/(x-1)^2 => x(x-1) = 0 => x =0 or x= 1

12.

Logx − log x − 1^2 = 2 log( x− 1)

Answer»

Answer:

I'll solve whatever I SEE here and understand:

logx - logx -1^2 = 2 log (X-1)

=> log x/(x-1) = log (x-1)^2

=> x/x-1 = 1/(x-1)^2

Answer» In mathematics, a rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number. DescriptionAn integer is a number that can be WRITTEN WITHOUT a fractional component. For example, 21, 4, 0, and −2048 are integers, while 9.75, 5+, and √2 are not. The set of integers consists of zero, the POSITIVE natural numbers, ALSO CALLED whole numbers or counting numbers, and their additive inverses. An integer (from the Latin integer meaning "whole") is a number that can be written without a fractional component. For example, 21, 4, 0, and −2048 are integers, while 9.75, 512, and √2 are not. the positive integers (whole numbers) 1, 2, 3, etc., and sometimes zero as well. Mark me brainliest

Answer» Answer: Important Polynomials Questions For Class 9- Chapter 2 (With Solutions) 1. Give an example of a monomial and a binomial having degrees as 82 and 99 respectively. Solution: An example of monomial having a degree of 82 = x82 An example of a binomial having a degree of 99 = x99 + x 2. Compute the value of 9x2 + 4y2 if xy = 6 and 3x + 2y = 12. Solution: Consider the equation 3x + 2y = 12 Now, square both sides: (3x + 2y)2 = 122 => 9x2 + 12xy + 4y2 = 144 =>9x2 + 4y2 = 144 – 12xy From the questions, xy = 6 So, 9x2 + 4y2 = 144 – 72 Thus, the value of 9x2 + 4y2 = 72 3. FIND the value of the polynomial 5x – 4x2 + 3 at x = 2 and x = –1 Solution: Let the equation be f(x) = 5x – 4x2 + 3 Now, for x = 2, f(2) = 5(2) – 4(2)2 + 3 => f(2) = 10 – 16 + 3 = –3 Or, the value of the polynomial 5x – 4x2 + 3 at x = 2 is -3 Similarly, for x = –1, f(–1) = 5(–1) – 4(–1)2 + 3 => f(–1) = –5 –4 + 3 = -6 4. Calculate the perimeter of a rectangle whose area is 25x2 – 35x + 12. Solution: Given, Area of rectangle = 25x2 – 35x + 12 We know, area of rectangle = length × breadth So, by factoring 25x2 – 35x + 12, the length and breadth can be obtained. 25x2 – 35x + 12 = 25x2 – 15x – 20X + 12 => 25x2 – 35x + 12 = 5x(5x – 3) – 4(5x – 3) => 25x2 – 35x + 12 = (5x – 3)(5x – 4) So, the length and breadth are (5x – 3)(5x – 4). Now, perimeter = 2(length + breadth) So, perimeter of the rectangle = 2((5x – 3)+(5x – 4)) = 2(5x – 3 + 5x – 4) = 2(10x – 7) = 20x – 14 So, the perimeter = 20x – 14 5. Find the value of x3 + y3 + Z3 – 3xyz if x2 + y2 + z2 = 83 and x + y + z = 15 Solution: Consider the equation x + y + z = 15 From algebraic identities, we know that (a + B + c)3 = a2 + b2 + c2 + 2(ab + bc + ca) So, (x + y + z)2 = x2 + y2 + z2 + 2(xy + yz + xz) From the question, x2 + y2 + z2 = 83 and x + y + z = 15 So, 152 = 83 + 2(xy + yz + xz) => 225 – 83 = 2(xy + yz + xz) Or, xy + yz + xz = 142/2 = 71 Using algebraic identity a³ + b³ + c³ – 3abc = (a + b + c)(a² + b² + c² – ab – bc – ca), x3 + y3 + z3 – 3xyz = (x + y + z)(x² + y² + z² – (xy + yz + xz)) Now, x + y + z = 15, x² + y² + z² = 83 and xy + yz + xz = 71 So, x3 + y3 + z3 – 3xyz = 15(83 – 71) => x3 + y3 + z3 – 3xyz = 15 × 12 Or, x3 + y3 + z3 – 3xyz = 180 hope it helps mark the answer as brainliest

Answer»

Answer:

Important Polynomials Questions For Class 9- Chapter 2 (With Solutions)

1. Give an example of a monomial and a binomial having degrees as 82 and 99 respectively.

Solution:

An example of monomial having a degree of 82 = x82

An example of a binomial having a degree of 99 = x99 + x

2. Compute the value of 9x2 + 4y2 if xy = 6 and 3x + 2y = 12.

Solution:

Consider the equation 3x + 2y = 12

Now, square both sides:

(3x + 2y)2 = 122

=> 9x2 + 12xy + 4y2 = 144

=>9x2 + 4y2 = 144 – 12xy

From the questions, xy = 6

So,

9x2 + 4y2 = 144 – 72

Thus, the value of 9x2 + 4y2 = 72

3. FIND the value of the polynomial 5x – 4x2 + 3 at x = 2 and x = –1

Solution:

Let the equation be f(x) = 5x – 4x2 + 3

Now, for x = 2,

f(2) = 5(2) – 4(2)2 + 3

=> f(2) = 10 – 16 + 3 = –3

Or, the value of the polynomial 5x – 4x2 + 3 at x = 2 is -3

Similarly, for x = –1,

f(–1) = 5(–1) – 4(–1)2 + 3

=> f(–1) = –5 –4 + 3 = -6

4. Calculate the perimeter of a rectangle whose area is 25x2 – 35x + 12.

Solution:

Given,

Area of rectangle = 25x2 – 35x + 12

We know, area of rectangle = length × breadth

So, by factoring 25x2 – 35x + 12, the length and breadth can be obtained.

25x2 – 35x + 12 = 25x2 – 15x – 20X + 12

=> 25x2 – 35x + 12 = 5x(5x – 3) – 4(5x – 3)

=> 25x2 – 35x + 12 = (5x – 3)(5x – 4)

So, the length and breadth are (5x – 3)(5x – 4).

Now, perimeter = 2(length + breadth)

So, perimeter of the rectangle = 2((5x – 3)+(5x – 4))

= 2(5x – 3 + 5x – 4) = 2(10x – 7) = 20x – 14

So, the perimeter = 20x – 14

5. Find the value of x3 + y3 + Z3 – 3xyz if x2 + y2 + z2 = 83 and x + y + z = 15

Solution:

Consider the equation x + y + z = 15

From algebraic identities, we know that (a + B + c)3 = a2 + b2 + c2 + 2(ab + bc + ca)

So,

(x + y + z)2 = x2 + y2 + z2 + 2(xy + yz + xz)

From the question, x2 + y2 + z2 = 83 and x + y + z = 15

So,

152 = 83 + 2(xy + yz + xz)

=> 225 – 83 = 2(xy + yz + xz)

Or, xy + yz + xz = 142/2 = 71

Using algebraic identity a³ + b³ + c³ – 3abc = (a + b + c)(a² + b² + c² – ab – bc – ca),

x3 + y3 + z3 – 3xyz = (x + y + z)(x² + y² + z² – (xy + yz + xz))

Now,

x + y + z = 15, x² + y² + z² = 83 and xy + yz + xz = 71

So, x3 + y3 + z3 – 3xyz = 15(83 – 71)

=> x3 + y3 + z3 – 3xyz = 15 × 12

Or, x3 + y3 + z3 – 3xyz = 180

hope it helps

Answer»

Answer:

A buys 20 SHARES , each shares 10 RS.

20 SHARE value = 20 × 10 = 200 Rs.

9% dividend = (109/100) ×200 = 218 Rs.

then he gets 12% = (112/100) × 218

then total share value = 244.16 Rs

Starting share value =200

Market share value = 244.16 Rs.

Therefore

present each share value = 244.16 / 20

each share value = 12.208 Rs.

Answer» Answer: Step-by-step explanation; let us assume the GIVEN no. is a RATIONAL no. therefore 3-4 root 2/7 =a/b. 3-4 root 2 =7a/b 4 root 2 =3 - 7a/b root 2 = (3 - 7a/b)/4 but root 2 is an irrational no. this CONTRADICTS our assumption. therefore the given no. is an irrational no.

Prove that (3 - 4 root 2) by 7 is an irrational number given that root 2 is an irrational number.Correct explanation will be marked as brainliest.

Answer»

Answer:

Step-by-step explanation;

let us assume the GIVEN no. is a RATIONAL no.

therefore 3-4 root 2/7 =a/b.

3-4 root 2 =7a/b

4 root 2 =3 - 7a/b

root 2 = (3 - 7a/b)/4

but root 2 is an irrational no.

this CONTRADICTS our assumption.

therefore the given no. is an irrational no.

40.	The zeroes of the polynomial xsquare - 3x - m(m+3)
Answer» ANSWER: pls MARK me as brainlist Step-by-step explanation: Given: equation x2 −3x−m(m+3)=0, where m is a constant To find the roots of the equation Sol: the given equation is of form ax 2+bx+C=0∴a=1,b=−3,c=−m(m+3) We know the roots of the equation can be find out using the formula, X= 2a−b± b 2−4ac Substituting the VALUES of a, b, c, we get x= 2−(−3)± (−3) 2−4(1)(−m(m+3) ⟹x= 23± 9+4m 2 +12m ⟹x= 23±(2m+3) or x= 23+(2m+3) ,x= 23−(2m+3) ⟹x=m+3,x=−m are the required roots of the equation

The zeroes of the polynomial xsquare - 3x - m(m+3)

Answer»

ANSWER:

pls MARK me as brainlist

Step-by-step explanation:

Given: equation x2 −3x−m(m+3)=0, where m is a constant

To find the roots of the equation

Sol: the given equation is of form ax 2+bx+C=0∴a=1,b=−3,c=−m(m+3)

We know the roots of the equation can be find out using the formula,

X= 2a−b± b 2−4ac

Substituting the VALUES of a, b, c, we get

x= 2−(−3)± (−3) 2−4(1)(−m(m+3)

⟹x= 23± 9+4m 2 +12m

⟹x= 23±(2m+3)

or x= 23+(2m+3)

,x= 23−(2m+3)

⟹x=m+3,x=−m are the required roots of the equation
