If the quadratic side is factorable, factor, then set each To solve quadratic equations, start by combining all of the like terms and moving them to one side of the equation. Then, factor the expression, and set each set of The objective of this tutorial is to solve quadratic equations by factoring. When a quadratic equation cannot be factorized, we can use the method of completing the square to solve the equation. Learn how with our examples.
First, you have to realize that 3 cannot be a correct answer because you cannot divide by zero. Then simply cross multiply and solve. (x-3) (x-3) =16. (x-3)^2 = 16 take SQRT of both sides.

A quadratic equation as you remember is an equation that can be written on the standard form a x 2 + b x + c = 0, w h e r e a ≠ 0 You know by now how to solve a quadratic equation using factoring. Another way of solving a quadratic equation is to solve it graphically. If a = 0, then it is not (strictly speaking) a quadratic equation. It's a linear equation, and the solution in that case is trivial to compute. Walter Roberson on 9 Nov 2011
