WebThe factored form of a quadratic equation helps in finding its roots or solutions. For example: As seen in the previous section, the factored form of x2 −5x+6 = 0 x 2 − 5 x + 6 = 0 is (x −2)(x −3) = 0 ( x − 2) ( x − 3) = 0. Now, when the product of two terms is 0 it means either of them could be 0. So,
