Answer:

=90 $x^{2}$ +2x+3

Step-by-step explanation:

Let’s simplify step-by-step.

2 $x^{2}$ + 82 $x^{2}$ + 8 − ( −6 $x^{2}$ − 2x + 5 )

Distribute the Negative Sign:

= 2 $x^{2}$ + 82 $x^{2}$ + 8 + − 1 ( − 6 $x^{2}$ − 2x + 5 )

= 2 $x^{2}$ + 82 $x^{2}$ + 8 + − 1( − 6 $x^{2}$ ) + − 1 ( −2x ) + ( − 1 ) ( 5 )

= 2 $x^{2}$ + 82 $x^{2}$ + 8 + 6 $x^{2}$ + 2x + − 5

Combine Like Terms:

= 2 $x^{2}$ + 82 $x^{2}$ + 8 + 6 $x^{2}$ + 2x + −5

= ( 2 $x^{2}$ + 82 $x^{2}$ + 6 $x^{2}$ ) + ( 2x ) + ( 8 + − 5 )

= 90 $x^{2}$ + 2x + 3
