Divide using synthetic division 3x^3 - 3x^2 -4x + 3 / x + 3

Question

A: 3x^2 - 12x + 32

B: 3x^2 - 12x + 32 r - 93

C: 3x ^2 + 6x - 40

D: 3x^2 + 6x - 40 r 99

Answer 1

Use the zero for synthetic division, -3

-3 | 3 -3 -4 3

-9 36 -96

3 -12 32 -93

B: 3x² - 12x + 32 r - 93

Answer 2

B is correct.

plug -3 into the cubic polynomial and you get -93. that's the remainder when you divide x+3 into the cubic

B is the only one with r -93
