If the quadratic factors easily, this method is very quick. How to identify the most appropriate method to solve a quadratic equation.Any other quadratic equation is best solved by using the Quadratic Formula.-4 a c<0\), the equation has \(2\) complex solutions. When x 3, the left hand side of the equation equals 2.This is not equal to the right hand side of the equation, 0.x 3 does not solve the equation.x 1 and x 2 solve the quadratic equation x 2 3x + 2 0.A quadratic equation will always have 2 values of x that solve the equation. It will be helpful to rewrite the equation if this occurs, e.g. If a term does not exist the coefficient is 0. It will also solve any other degree polynomial. If the equation fits the form ax 2 = k or a( x − h) 2 = k, it can easily be solved by using the Square Root Property. If you have a TI-84 calculator (graphing) there is a program named SOLVER that will solve a quadratic equation. if b 2 − 4 ac Solve your quadratic equations step-by-step Solves by factoring, square root, quadratic formula methods.

Mathematicians look for patterns when they do things over and over in order to make their work easier. By the end of the exercise set, you may have been wondering ‘isn’t there an easier way to do this?’ The answer is ‘yes’. When we solved quadratic equations in the last section by completing the square, we took the same steps every time.
