Multiply the polynomials.

(x – 5)(x2 + 4x – 2)

A.
x3 – x2 – 20x + 10

B.
x3 – x2 – 22x + 10

C.
x3 + 4x2 – 22x + 10

D.
x3 + 4x2 – 20x + 10

B

Step-by-step explanation:

(x-5)(x^2 + 4x - 2).

Distribute the x and -5 with the x^2, 4x and -2:

x^3 + 4x^2 -2x -5x^2 -20x + 10

Add like terms:

x^3 - x^2 - 22x + 10

B is the answer.
