What is the remainder r when the polynomial p(x) is divided by (x + 1)? is (x + 1) a factor of p(x)? p(x) = -3x4 + 2x3 - x2 + 6

(x+1) is a factor with remainder 0.

Step-by-step explanation:

We divide (x+1) into the polynomial through long division or synthetic. We choose long division and look for what will multiply with (x+1) to make the polynomial .

We subtract this from the original .

This leaves . We repeat the step above.

.

We subtract this from . We repeat the step above.

.

We subtract this from . We repeat the step above.

.

We subtract this from . There is no remainder. This means (x+1) is a factor.
