This method that can be used to solve quadratic equations is extracting square roots. The fact remains that all variables come in the squared form, which is what we want. Watch a Khan Academy Video Length: 11:03 . Tap for more steps. Quadratic equations are the equations of type ax 2 + bx + c = 0 where x is unknown and a, b, c are known real numbers and a should not be zero. Here I have a quadratic equation with no b term so right away I'm thinking I'm going to want to take the square root of both sides of an equation but first I want to get x isolated. The quadratic equation x = c, where c is a real number, has two solutions x = c and x = - c or simply x = c . How do you extract square root and factor quadratic equation? Now check whether the solutions satisfy the original equation because squaring can introduce spurious solutions. If you square '3' or '-3', both of them will result the same value '9'. Use the square root property to solve for the roots of the following quadratic equations. Quadratic Equations that can be written in the form = can be solved by applying the following properties: 1.
