Answer:

X2-3X+2

Step-by-step explanation:

  1. let the zeroes be U and V
  2. given that U+V=3 andU-V=-1

by SOLVING ,

U+V=3

U-V=-1

we get,

U=1 and V=2

3.by QUADRATIC FORMULA

16 X square + 4 x minus 2​

Answer»

Step-by-step explanation:

16x2 + 4x - 2 =0.

  2 • (8x2 + 2x - 1) =0.

8x^2 + 2x - 1= 0/2.

8x^2 + 2x - 1 = 0.

Factoring  8x2 + 2x - 1 

The first term is,  8x2  its coefficient is  8 .

The middle term is,  +2x  its coefficient is  2 .

The last term, "the constant", is  -1 

Step-1 : MULTIPLY the coefficient of the first term by the constant   8 • -1 = -8 

Step-2 : FIND two FACTORS of  -8  whose sum equals the coefficient of the middle term, which is   2 .

-2   +   4   =   2   That's it

Step-3 : Rewrite the polynomial SPLITTING the middle term using the two factors found in step 2 above,  -2  and  4 

                     8x2 - 2x + 4x - 1

Step-4 : Add up the first 2 terms, pulling out like factors :

                    2x • (4x-1)

              Add up the last 2 terms, pulling out common factors :

                     1 • (4x-1)

Step-5 : Add up the four terms of step 4 :

                    (2x+1)  •  (4x-1)

             Which is the desired factorization

2x+1 =0 (or) 4x-1 =0.

2x=-1 (or) 4x = 1

x= -1/2 (or) x= 1/4.

Prove that sigma (fixi-x bar) =0

Answer»

LET TOTAL number of observation = N

Given MEAN of n observations  = X

then (x1 +x2 +x3 +......+xn )/n = X

 => x1 +x2 +x3 +......+xn  = n*X

Now ∑ (xi - X) = {(x1 -X) + (x2 -X) + (x3 -X)+......+(xn -X)} - n*X

                    = (x1 +x2 +x3 +......+xn ) - n*X

                    = n*X - n*X

                    = 0

So ∑ (xi - X) = 0

Hope you understood the sequence of steps.  

All the best.

What is the value of sin18​

Answer»

\bold{ANSWER}

Let A = 18°   

                       

Therefore, 5A = 90° 

⇒ 2A + 3A = 90˚

⇒ 2θ = 90˚ - 3A

Taking sine on both sides, we GET 

sin 2A = sin (90˚ - 3A) = COS 3A 

⇒ 2 sin A cos A = 4 cos^3 A - 3 cos A

⇒ 2 sin A cos A - 4 cos^3A + 3 cos A = 0 

⇒ cos A (2 sin A - 4 cos^2 A + 3) = 0 

Dividing both sides by cos A = cos 18˚ ≠ 0, we get

⇒ 2 sin θ - 4 (1 - sin^2 A) + 3 = 0

⇒ 4 sin^2 A + 2 sin A - 1 = 0, which is a QUADRATIC in sin A

Therefore, sin θ = \(\FRAC{-2 \pm \sqrt{- 4 (4)(-1)}}{2(4)}\)

⇒ sin θ = \(\frac{-2 \pm \sqrt{4 + 16}}{8}\)

⇒ sin θ = \(\frac{-2 \pm 2 \sqrt{5}}{8}\)

⇒ sin θ = \(\frac{-1 \pm \sqrt{5}}{4}\)

Now sin 18° is positive, as 18° lies in FIRST quadrant.

Therefore, sin 18° = sin A =\(\frac{-1 \pm \sqrt{5}}{4}\)

Find the middle term of the ap 213,205,197,....,37

Answer»

Answer:

125

Step-by-step explanation:

In this AP(213,205,197,....,37),

first term'a'=213

common difference'd'=205-213=(-8)

Tn=37..........(a)

Now, Tn =a+(n-1)d

213+(n-1)(-8)

213-8n+8

Tn=221-8n

using(a)

37=221-8n

37-221=(-8n)

(-184)=(-8n)

184/8=n

23=n

hence this AP contains 23 TERMS..

middle term=n+1/2. (for odd numbers)

middle term=23+1/2

=24/2

=12TH term

so, the middle term of this AP is its 12th term..

12th term=a+(12-1)d

=213+11*(-8)

=213-88

=125

so the middle term of this AP is 12th term

and the value of 12th term is 125..

5.There are two numbers such that sum of the numbers is 50 and the difference is 14 . Find the difference of their cubes.

Answer»

Step-by-step EXPLANATION:

Let the no. be x and y

x+ y= 50. (1)

x-y= 14

x=14+y. (2)

put 2 in 1

14+y+y= 50

14+2y= 50

2y= 36

y= 18

x+y=50

x+ 18= 50

x= 32

a3-b3= (a-b) (a2+b2+ab)

= (32-18)[(18)^2 +(32)^2 + (32)(18)]

= 14[ 324 +1024 + 576]

= 14(1924)

= 26936
