3.

Some Import1. Find the zeroes of the quadratic polynomialp(x) = 9x2 - 42. Find the quadratic polynomial whose zeroes are1 and -3Evergreen Sell-Study in Mathematics

Answer»

SOLUTION 1:

$\bf{\red{\underline{\bf{Given\::}}}}$

The quadratic POLYNOMIAL p(X) = 9x² - 4.

$\bf{\red{\underline{\bf{To\:find\::}}}}$

The ZEROES.

$\bf{\red{\underline{\bf{Explanation\::}}}}$

We have p(x) = 9x² - 4

Zero of the polynomial p(x) = 0

So;

$\longrightarrow\sf{9x^{<klux>2</klux>} -4=0}\\\\\longrightarrow\sf{(3x)^{2} -(2)^{2} =0}\\\\\longrightarrow\sf{(3x+2)(3x-2)=0\:\:\:[\therefore\:using\:a^{2} -b^{2} ]}\\\\\longrightarrow\sf{3x+2=0\:\:\:Or\:\:\:3x-2=0}\\\\\longrightarrow\sf{3x=-2\:\:\:Or\:\:\:3x=2}\\\\\longrightarrow\sf{\orange{x=\dfrac{-2}{3} \:\:\:Or\:\:\:x=\dfrac{2}{3} }}$

∴ The α = -2/3 and β = 2/3 are the zeroes of the polynomial.

Solution 2:

$\bf{\red{\underline{\bf{Given\::}}}}$

We have α = 1 and β = -3.

$\bf{\red{\underline{\bf{To\:find\::}}}}$

The quadratic polynomial.

$\bf{\red{\underline{\bf{Explanation\::}}}}$

$\star\:{\green{\underline{\boldsymbol{Sum\:of\:the\:zeroes\::}}}}}$

$\longrightarrow\sf{\alpha +\beta =\dfrac{-b}{a} }\\\\\\\longrightarrow\sf{\alpha +\beta= 1+(-3)}\\\\\\\longrightarrow\sf{\alpha +\beta =1-3}\\\\\\\longrightarrow\sf{\pink{\alpha +\beta =-2}}$

$\star\:{\green{\underline{\boldsymbol{Product\:of\:the\:zeroes\::}}}}}$

$\longrightarrow\sf{\alpha \beta =\dfrac{c}{a} }\\\\\\\longrightarrow\sf{\alpha \beta =1\times -3}\\\\\\\longrightarrow\sf{\pink{\alpha \beta =-3}}$

Now;

$\boxed{\bf{The\:required\:quadratic\:polynomial\::}}}}$

$\longrightarrow\sf{x^{2} -(sum\:of\:the\:zeroes)+(product\:of\:the\:zeroes)}\\\\\longrightarrow\sf{x^{2} -(-2)x+(-3)=0}\\\\\longrightarrow\sf{\pink{x^{2} +2x-3=0}}$

1. In a lottery, a total of 200 prizes are to be given. A prize is either of Rs. 500or Rs. 100. Find the number of each type of prizes if the total prize moneyis Rs. 50,000[Ans: 75 and 125]

Answer»

ANSWER:

STEP-BY-STEP-EXPLANATION

Answer:

Step-by-step explanation:

TOTAL prize money = 50000

Let the NUMBER of 500 rs prize be x

Hence the number of 100 rs prize = 200 - x

Total amount for 500 rs prizes = 500 × x = 500 x

Total amount for 100 rs prizes = (100 × (200 - x) = 20000 -1 00x

=> 500x + 20000 - 100x = 50000

=>400x = 50000-20000

400x = 30000

x = 30000/400

x = 75

No of 500 rs prize ,= 75

No of 100 rs prize = 200 - 75 =125

Hope it is clear

16.

If x-1/x=√5 find the value of x^2+1/x^2 and x^4+1/x^4❤❤ I love you❤

Answer»

Answer:

X+1/x=√5 (GIVEN)

Now,

(X+1/x)^2 = x^2 + 1/x^2 + 2

(√5)^2 = x^2 + 1/x^2 + 2

5 = x^2 + 1/x^2 + 2

5-2 = x^2 + 1/x^2

3 = x^2 + 1/x^2

(X^2 +1/x^2)^2 = (x^2)^2 +(1/x^2)^2 + 2

(3)^2 = x^4 + 1/x^4 + 2

9 = x^4 + 1/x^4 + 2

9 - 2 = x^4 + 1/x^4

7 = x^4 + 1/x^4
