How to find the x intercepts (solutions) of a quadratic in vertex form

The video tutorial explains how to find the X intercepts of a quadratic equation by setting y=0. It contrasts solving quadratics in standard form, which requires factoring, with solving in vertex form, which uses reverse operations. The tutorial outlines the steps to solve quadratics in vertex form, including undoing addition, subtraction, multiplication, and division, and taking the square root of both sides. The process concludes with finding the X intercepts and expressing them as coordinate points.

What steps must be taken after undoing addition and subtraction in the process of solving a quadratic equation?

How do you express the X intercepts as coordinate points after solving the equation?
