In this video I show you how to use the fundamental theorem of algebra to factor ANY polynomial of the form ax^2 + bx + c, especially when the coefficient a is not 1. For this we use the square root formula to find the zeros/roots of the polynomial. This technique does not require trial and error and is more robust as a factoring procedure, since it works when the polynomial coefficients are very large numbers, and when it is not possible to use the remarkable product of algebra.
