Question

2 multiple choice 1 point which expression is equivalent to $10x^2 - (3x + 2x^2) + 6 - (-5x + 9)$?

Explanation:

Step1: Distribute negative signs

$10x^2 - 3x - 2x^2 + 6 + 5x - 9$

Step2: Combine like $x^2$ terms

$10x^2 - 2x^2 = 8x^2$

Step3: Combine like $x$ terms

$-3x + 5x = 2x$

Step4: Combine constant terms

$6 - 9 = -3$

Step5: Combine all simplified terms

$8x^2 + 2x - 3$

Answer:

$\boldsymbol{8x^2 + 2x - 3}$
