Question

is the term (x+2) a factor of f(x)=x^3-10x^2+27x-12

Answer 1

You would need to divide x^3 - 10x^2 + 27x - 12 by x+2 and see if you have a remainder. if there is no remainder then it is a factor.

Answer 2

I did that but I got a really weird answer

Answer 3

use the remainder theorem

Answer 4

if -2 is a root of f(x), then x+2 is a factor

Answer 5

thanks :)
