question 39 of 40
victoria was given the expression $-3x + x^2 - 8 + 4x - 3x^2 - 2$ and asked to simplify it. how can she simplify the expression?

a. $-4x^2 - 7x - 6$

b. $2x^2 - x + 10$

c. $-2x^2 + x - 10$

d. $4x^2 + 7x + 6$

Explanation:

Step1: Group like terms

$x^2 - 3x^2 - 3x + 4x - 8 - 2$

Step2: Combine $x^2$ terms

$x^2 - 3x^2 = -2x^2$

Step3: Combine $x$ terms

$-3x + 4x = x$

Step4: Combine constants

$-8 - 2 = -10$

Step5: Form simplified expression

$-2x^2 + x - 10$

Answer:

C. $-2x^2 + x - 10$
