Real and equal roots example

WebExample: Let us find the roots of the same equation that was mentioned in the earlier section x 2 - 3x - 4 = 0 using the quadratic formula. a = 1, b = -3, and c = -4. ... For D > 0, the roots are real and distinct, for D = 0 the roots are real and equal, and for D < 0, the roots do not exist or the roots are imaginary complex numbers. With the ... 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,
