Can You Factor Using The Quadratic Formula Sal solves the equation s 2 2s 35 0 by factoring the expression on the left as s 5 s 7 and finding the s values that make each factor equal to zero Created by Sal Khan and Monterey Institute for Technology and Education
Factoring quadratics is a method of expressing the quadratic equation ax 2 bx c 0 as a product of its linear factors as x k x h where h k are the roots of the quadratic equation ax 2 bx c 0 This method is also is called the method of factorization of quadratic equations How to Solve Quadratic Equations using Factoring Method This is the easiest method of solving a quadratic equation as long as the binomial or trinomial is easily factorable Otherwise we will need other methods such as completing the square or using the quadratic formula
