How to Solve Quadratic Equations using Factoring Method. To be in the correct form, you must remove all parentheses from each side of the equation by distributing, combine all like terms, and finally set the equation equal to zero with the terms written in descending order. Solving Quadratic Equations by Factoring. Here are the steps required for Solving Quadratics by Factoring: Step 1: Write the equation in the correct form. The standard form of any quadratic equation must be expressed as AX²+ BX + C≠0, where A, B, and C are values, except that A can't be equal to zero, and X is unknown (yet to be solved). With the equation in standard form, let’s review the grouping procedures: With the quadratic in standard form, $a{x}^{2}+bx+c=0$, multiply $a\cdot c$. EXAMPLE 5 Using Zeros to Write Function Rules Write a quadratic function in standard form with zeros 2 and -1. x = 2 or x = -1 Write the zeros as solutions for two equations. We will look at each of these steps as we proceed to solve $$x^{2}=100$$. Check to make sure that the quadratic equation is in standard form and is equal to zero, if not, rearrange the equation to bring all terms to the left hand side. Played 50 times. Hence, r = -7, 9.
