How to Solve Quadratic Equations using Factoring Method This is the easiest method of solving a quadratic equation as long as the binomial or trinomial is easily factorable. Otherwise, we will need other methods such ascompleting the squareor using thequadratic formula. The following diagram illustr...
Solve each of the following quadratic equations by factoring. Example 1 : x2 + 5x + 6 = 0 Solution : Step 1 : In the quadratic equation x2 + 5x + 6 = 0, multiply the coefficient of x2, 1 and the constant term 6. = 1 x 6 = 6...
Solving quadratic equations by factoring: x² + 3x – 10 = 0 Since this equation is factorable it can be solved by simply factoring. (x – 2)(x + 5) = 0 The quadratic formula method of solving quadratic equations will be reviewed as a possible alternative method of solving non-factor...

First, simplify by putting all terms on one side and combining like terms. Now, factor. To check, 2x2+ 2x– 1 =x2+ 6x– 5 The quadratic formula Many quadratic equations cannot be solved by factoring. This is generally true when the roots, or answers, are not rational numbers. A seco...
This module is from Elementary Algebra by Denny Burzynski and Wade Ellis, Jr. Methods of solving quadratic equations as well as the logic underlying each method are discussed. Factoring, extraction of roots, completing the square, and the quadratic formula are carefully developed. The zero-factor...
