Completing the square is used to derive the quadratic formula from ax^2 + bx + c = 0. After dividing by a and completing the square, (x + b/2a)^2 equals:

Question

Accepted Answer

b^2 - 4ac/4a^2. x^2 + b/ax = -c/a, add b^2/4a^2: (x + b/2a)^2 = b^2/4a^2 - c/a = b^2 - 4ac/4a^2.

Completing the square is used to derive the quadratic formula from $a x^{2} + b x + c = 0$ .
After dividing by a and completing the square $, (x + \frac{b}{2 a})$ ² equals:
