Suppose we are asked to solve the quadratic equation. Graphically since a quadratic equation represents a parabola. Now if this is the first time that youve seen this type of whats essentially a quadratic equation you might be tempted to try to solve for s using traditional algebraic means but the best way to solve this especially when its explicitly equal to 0 is to factor the left-hand side and then think about the fact that those binomials that you factor into that they have to be equal to 0.
Thus xfrac-52 Or x frac52 Example 2.
Set each factor equal to zero. If you want to know how to master these three methods just follow these steps. You can use the Mathway widget below to practice solving quadratic equations by factoring. 1 to factor the quadratic equation if you can do so 2 to use the quadratic formula or 3 to complete the square.
