Question

A = $7 straight x squared – 3 straight x plus 10$ ; B = $negative 4 straight x squared plus 6 straight x – 4$
Find A – B. The answer should be in standard polynomial form.

$10 x^{2} + 8 x + 10$
$11 x^{2} - 9 x + 14$
$8 x^{2} + 11 x + 15$
$12 x^{2} - 4 x + 11$

hint Hint:

Combine like terms

The correct answer is: $11 straight x squared – 9 straight x plus 14$

A = $7 straight x squared – 3 straight x plus 10$
B = $negative 4 straight x squared plus 6 straight x – 4$
$equals left parenthesis 7 straight x squared – 3 straight x plus 10 right parenthesis – left parenthesis negative 4 straight x squared plus 6 straight x – 4 right parenthesis$
= $7 x squared minus 3 x plus 10 plus 4 x squared minus 6 x plus 4$
$equals 11 straight x squared – 9 straight x plus 14$

What is the missing term in the equation?
(___+ 7) + (2x – 6) = -4x + 1
