Khan Academy: Algebra Ii: Zeros of Polynomials: Matching Equation to Graph
When we are given the graph of a polynomial, we can deduce what its zeros are, which helps us determine a few factors the polynomial's equation must include. [3:00]

Khan Academy: Algebra Ii: Zeros of Polynomials Introduction
The zeros of a polynomial p(x) are all the x-values that make the polynomial equal to zero. They are interesting to us for many reasons, one of which is that they tell us about the x-intercepts of the polynomial's graph. We will also see...
