Use the Factor Theorem to determine whether x+1 is a factor of p(x)=2x^4+x^3-4x-5
Specifically, evaluate p at the proper value, and then determine whether x+1 is a factor.

by the Theorem, if (x-a) is a factor, then p(a) = 0
p(-1) = 0 so (x+1) is a factor of p(x)
p(-1) = 0 so (x+1) is a factor of p(x)
