Question

The Factor Theorem

Use the Factor Theorem to determine whether x+2 is a factor of P(x) = -x4 - x3 + 3x + 5

Specifically, evaluate P at the proper value, and then determine whether x-1 is a factor.



p(?) = ?
is p(x) a factor of x + 2 or not

Answer 1

p(-2) = 13 not a factor

Explanation:

because is you use :

x+2=0

x= -2

then p(+2) = 13 if an factor it must be equal to 0
