    Synthetic Division

    So my problem is
    "Use synthetic division to show that X is a solution of the third degree polynomial equation, and use the result to factor the polynomial completely. List all the real zeros."

    Polynomial Equation: x^3 + 7x + 6 = 0 Value of X = 2

    I don't really understand what I'm bein asked to do..

    If you know one of the zeroes of a polynomial, you can divide synthetically by it to reduce the polynomial one degree. So a 3rd degree becomes a 2nd degree. However, 2 is not a zero of this polynomial and neither is -2. Did you copy it wrong?
