2 hours ago Using the identity a2 + 2ab + b2 = (a + b)2, [x + (b/2a)]2 = (-c/a) + (b2/4a2) [x + (b/2a)]2 = (b2 – 4ac)/4a2. Take the square root on both sides, x + b 2 a = ± b 2 − 4 a c 2 a. Therefore, x = − b ± b 2 − 4 a c 2 a. This is the most commonly used method to derive the quadratic formula in maths.

2 hours ago Quadratic Formula Proof. Consider an arbitrary quadratic equation: ax 2 + bx + c = 0, a ≠ 0. To determine the roots of this equation, we proceed as follows: 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
