This Professor’s ‘Amazing’ Trick Makes Quadratic Equations Easier
WebTo solve the quadratic equation using completing the square method, follow the below given steps. First make sure the equation is in the standard form: ax 2 + bx + c = 0 Now, divide the whole equation by a, such that the coefficient of x 2 is 1. Write the equation with a constant term on the Right side of equation WebConsider a quadratic equation ax 2 + bx + c = 0, a ≠ 0. To determine the roots of this equation, we simplify it as follows: ax 2 + bx + c = 0 ax 2 + bx = -c x 2 + bx/a = -c/a Now, we express the left-hand side as a perfect square, by introducing a new term (b/2a) 2 on both sides: x 2 + bx/a + (b/2a) 2 = -c/a + (b/2a) 2 in a lurch
