3 Ways to Solve Quadratic Equations - wikiHo

You can also solve quadratic equations by using the Quadratic Formula and by Factoring. For right now, let's focus our attention on solving simple quadratic equations using a few strategies that you are already familiar with. There is, of course, one new skill that you must apply. That is using square roots The quadratic formula helps us solve any quadratic equation. First, we bring the equation to the form ax²+bx+c=0, where a, b, and c are coefficients. Then, we plug these coefficients in the formula: (-b±√ (b²-4ac))/ (2a). See examples of using the formula to solve a variety of equations

The Quadratic Formula Sometimes when we do not find 2 separate values of a variable applying any of the above methods then we use another technique which is known as the quadratic formula.
