Question

Use the Remainder Theorem to find the remainder when P(x) = x4 – 9x3 – 5x2 – 3x + 4 is divided by x + 3

Answer 1

remainder theorem states,
if you divide P(x) by (x+a)
then the remainder is
P(-a)

Answer 2

so, substitute "-3" for x in P(x) and get the answer.

Answer 3

where did you get the -3?

Answer 4

check wit hthe previous line

Answer 5

x+3=0
x=-3
