Transform the equation so that the quadratic term and the linear term equal a constant. ( ' ) Steps to solve an equation by completing the square: 1. Let us discuss in this section the different methods of solving quadratic equations. This method may be used to solve all quadratic equations. In elementary algebra, the quadratic formula is a formula that provides the solution(s) to a quadratic equation.There are other ways of solving a quadratic equation instead of using the quadratic formula, such as factoring (direct factoring, grouping, AC method), completing the square, graphing and others. A collection of EIGHT FULL LESSONS, which could definitely be extended to at least 10-11 lessons for the right classes, on solving quadratic equations by. There are other ways of solving a quadratic equation instead of using the quadratic formula, such as factoring (direct factoring, grouping, AC method), completing the square, graphing and others. Thus, equations a, c, and d are all quadratic equations. The quadratic function y 1 / 2 x 2 5 / 2 x + 2, with roots x 1 and x 4.
