Finding b in quadratic equation
WebConsider a quadratic equation ax 2 + bx + c = 0, where a, b, and c are real and a ≠ 0. The expression can be further rewritten as: a [ (x + b/2a) 2 – (D/4a 2 )] = 0. The above quadratic equation represents a parabola … WebThere are many ways to solve it, here we will factor it using the "Find two numbers that multiply to give a×c, and add to give b " method in Factoring Quadratics: a×c = −15, and b = −14. The factors of −15 are: −15, −5, −3, −1, 1, 3, 5, 15 By trying a few combinations we find that −15 and 1 work (−15×1 = −15, and −15+1 = −14)
