f(x)=x^3+8x^2-18x+20; x-10

I have a doubt in my answer, i determined that x-10 is not a factor... am i right? please verify as my exam is tomorrow night at college. thank you for your time and hard work:)

**MathMate**, Saturday, March 13, 2010 at 7:52pmIt can be shown that x-10 is not a factor of x^3+8x^2-18x+20. So your are correct.

If you wish, you could try (x+10) and show that it is a factor of x^3+8x^2-18x+20.
