Lesson Summary:

In this lesson, we learn how to use the quadratic formula to solve quadratic equations in standard form. We simplify the problem and get it in the form AX squared plus BX plus C, eliminating any fractions. Then we factor out the solution by factoring the numerator and denominator, getting two solutions for X. The key takeaway is to clear the fractions first before plugging in values of A, B, and C.
