How do you determine the zeros of a polynomial given one factor?

Back

You can use synthetic division to divide the polynomial by the given factor and then find the zeros of the resulting polynomial.

If (x - 5) is a factor of f(x) = x^3 - 2x^2 - 13x - 10, what are the other factors?

Back

The other factors are (x + 2) and (x + 1), so f(x) = (x - 5)(x + 2)(x + 1).
