Hello, pyrogurl6989!

I will assume you know the Remainder Theorem and the Factor Theorem.

1) Use the remainder theorem and the factor theorem to determine

whether is a factor of

Since

. . then: .(A) The remainder is 0, and therefore is a factor of

2) Use the remainder theorem to determine the remainder

when is divided by

Since , then the remainder is

3)Use the remainder theorem and the factor theorem to determine

whether is a factor of

Since

. . then: .(A) The remainder is 0, and therefore is a factor of
