so here is the basics if (x -2) is a factor x = 2 is a zero substitute f(2)=(2)3+7(2)2+14(2)+8 its a positive answer... so not a factor... try (x + 2) which means x - 2 is a zero substitute and check f(−2)=(−2)3+7(−2)2+14(−2)+8 if you evaluate it you'll get f(-2) = 0 so (x + 2) is a binomial factor. hope this makes sense

Have one more question: did I do this one right?? What is the quotient when x^3 − 5x^2 + 3x − 8 is divided by x − 3?
