Question

Subtract these polynomials

Answer 1

2x^2 + 3 Answer D

Explanation:

(3x^2 + 2x + 4) - (x^2 + 2x + 1)

(3x^2 + 2x + 4) + (-1)(x^2 + 2x + 1)

Distribute the "-1"

(3x^2 + 2x + 4) + ( -x^2 + (-2x) + (-1))

(3x^2 + 2x + 4) + (-x^2 - 2x - 1)

3x^2 + 2x + 4 - x^2 -2x -1

Regroup

3x^2 - x^2 + 2x - 2x + 4 - 1

Combine like terms

2x^2 + 0x + 3

2x^2 + 3
