How to Solve Quadratic Equations using Factoring Method
As long as the binomial or trinomial is factorable, this is the simplest technique of solving a quadratic problem. Other approaches, such as completing the square or applying the quadratic formula, will be required otherwise.
Solving factored quadratic equations
Suppose we are asked to solve the quadratic equation (x - 3) (x + 2) = 0
This is a product of two expressions that is equal to zero. Note that any x value that makes either ( x - 3)(x + 2) zero, will make their product zero.
( x - 3)(x + 2) = 0
x - 3 = 0 x + 2 = 0
x = 3 x = -2
Substituting either x = 3 or x = -2, into the equation will result in the true statement 0=0 , so they are both solutions to the equation.
Of course, not all quadratic equations are factored out. Most equations need to be factored out before you can solve for the roots.
