Question

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. -2x^2+x-10
B. 2x^2-x+10
C. -4x^2-7x-6
D. 4x^2+7x+6

Answer 1

A.

Explanation:

Organize the terms and you have this:

(-3x^2+x^2)+(4x-3x)+(-8-2)

The equal terms, i.e the terms with the same exponent (the ones that are in parentheses) are reduce:

(-3x^2+x^2)=-2x^2

(4x-3x)=x

(-8-2)=-10

Then

-2x^2+x-10
