Learn Guitar FREE on iPhone & iPad: bit.ly Allison Moffett, host of Mahalo’s Math Channel, shows how to use the quadratic formula to solve quadratic equations. She explains the formula and provides a visual example by solving a sample quadratic equation. This is part of a series of instructional videos available on Mahalo.com’s channel on YouTube. If you are taking an intermediate algebra class, you will have to know how to solve quadratic equations. This equation is in the form ax² + bx + c = 0. Quadratic equations are also known as equations of the second degree because they contain a term that is squared.library.thinkquest.org A quadratic equation has two solutions, also known as roots. The reason for this is because the equation can be factored as (x − a)(x − b), with “a” and “b” being the two roots. www.themathpage.com are two ways to solve a quadratic equation. One way is to factor the equation. The second is to use the quadratic formula. Both methods will produce the roots of the equation, but the quadratic formula is used most often in instances when the equation cannot be easily factored.www.purplemath.com Step 1: Put Equation in Standard Quadratic Form ——————————————————————— There will be equations that may not look like they are quadratic equations because they are not in the exact form of ax² + bx + c = 0. To make sure you are working with a quadratic equation, it is a good idea to see if the equation can be
