Question

Subtract these polynomials.

(3x² + 2x + 4) - (x² + 2x + 1) =
A. 2x² + 4x + 5
B. 2x2 + 5
OC. 2x² + 4x +3
D. 2x² + 3

Answer 1

D

Explanation:

(3x² + 2x + 4) - (x² + 2x + 1) rearrange so that like terms are together

3x² - x² + 2x - 2x + 4 - 1

= 2x² + 0 + 3

= 2x² + 3

Correct answer is choice D
