Zeros, Roots and X-Intercepts: What are they and How Do I Find Them

Explains what the zeros, roots and X-Intercepts of a Parabola are, and how to find them if you are given the intercept form, the vertex form, the standard form, and even how to find them if you are asked to Solve By Graphing. Show how to solve for the zeros of a function on a graphing calculator, reviews factoring parabolas in standard form and solving for the roots of a parabola when you are given the vertex form. Also contains links to factoring using the x-method and factoring by grouping.
