Question

Which is a factor of P(x) = x4 - 3x3 - x2 - 11x - 4?
A) (x + 2)
B) (x + 1)
C) (x + 4)
D) (x - 4)
Want to make sure i get this one right is it D?

Answer 1

please help!

Answer 2

is it D?!

Answer 3

let's check if it's D


if it was, then P(4) = 0


So P(4) = (4)^4-3(4)^3-(4)^2-11(4)-4


P(4) = 256-3(64)-16-11(4)-4


P(4) = 256-192-16-44-4


P(4) = 0


So because the remainder is 0, x-4 is a factor

Answer 4

so yes it is D!!! : D
