You are given two zeros but a polynomial of degree 3 should have 3 zeros. we need the third zero. The key is to understand when a zero is complex or imaginary, like 7i, then its conjugate, -7i, will also be a zero. So we now have our three zeros: -2, 7i and -7i. With these zeros we can write the equation: All that is left is to simplify.
