Answer 1

Answer:

This implies that

x2+2ax=4x−4a−13

or

x2+2ax−4x+4a+13=0

or

x2+(2a−4)x+(4a+13)=0

Since the equation has just one solution instead of the usual two distinct solutions, then the two solutions must be same i.e. discriminant = 0.

Hence we get that

(2a−4)2=4⋅1⋅(4a+13)

or

4a2−16a+16=16a+52

or

4a2−32a−36=0

or

a2−8a−9=0

or

(a−9)(a+1)=0

So the values of a are −1 and 9.

Answer 2

From the sum of x² + x + 1 and x² - x + 1 , we got 2x² + 2 and then subtract -x² - x + 1 from 2x² + 2 . THE ANSWER IS 3x² + 1x + 1 . PLEASE MARK ME BRAINLIEST ANSWER AND FOLLOW ME .PLEASE FOLLOW ME !!
