Answer 1

I hope this helps you




2x^2-7x+5+6x^2+4x+2



8x^2-3x+7

Answer 2

Answer:  The correct option is

(D) $8x^2-3x+7.$

Step-by-step explanation:  We are given to subtract the following two quadratic expressions :

$S=(2x^2-7x+5)-(-6x^2-4x-2)~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

To subtract the given expressions, we should subtract the coefficients of the same powers of unknown variable x.

The subtraction (i) is as follows :

$S\\\\=(2x^2-7x+5)-(-6x^2-4x-2)\\\\=2x^2-7x+5+6x^2+4x+2\\\\=8x^2-3x+7.$

Thus, the required answer is $8x^2-3x+7.$

Thus, (D) is the correct option.
