Answers

  1. Answer:

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

    Step-by-step explanation:

    Let’s simplify step-by-step.

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

    Distribute the Negative Sign:

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

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

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

    Combine Like Terms:

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

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

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