5: ROOTS OF A QUADRATIC EQUATION
irp-cdn.multiscreensite.comRoots of a quadratic equation (∝ *+, .) A quadratic equation in x is of the general form , where a, b and c are constants. 2 If we divide each term by a, then the quadratic equation can be expressed in an equivalent form with the coefficient of x2 is equal to one as shown below. Solution Now consider ∝ and 0 as the roots of the quadratic .
