Question

According to the synthetic division below, which of the following statements are true?

Check all that apply.

Answer 1

The answers are A, C and D

Answer 2

A, C, and D

Explanation:

The -4 means that when x=-4, x+?=0

Hence, x+4=0 when x=-4 ==> -4+4=0 ==> Hence -4 is a root ==> A and D

so x+4 is a factor of 3x^2 + 7x + 20

The '3 -5 0' part means 3x-5 with no remainder. ==> C

If there wasn't a zero at the end, there would be remainder to the quotient.
