Answer 1

Answer:

C. -x^2-x+9

Step-by-step explanation:

Combine Like Terms:

what we have 2x^2+6x−7x+8−3x^2+1

=(2x^2−3x^2)+(6x+−7x)+(8+1)

=−x^2+−x+9

Answer 2

Answer:

$-x^2-x+9$

Step-by-step explanation:

$2x^{2} +6x-7x+8-3x^2+1$

$2x^{2} +6x-7x+9-3x^2$     Add 8 + 1

Combine like terms

$2x^{2} +6x-7x+9-3x^2$     $6x-7x=-x$

$2x^2-x+9-3x^2$

Combine like terms

$2x^{2} -x+9-3x^2$              $2x^2-3x^2$

$-x^2-x+9$
