What is the quadratic formula used to solve ax^2 + bx + c = 0?
Ax = (-b ± sqrt(b^2 - 4ac)) / 2a
Bx = (b ± sqrt(b^2 - 4ac)) / 2a
Cx = (-b ± sqrt(b^2 + 4ac)) / 2a
Dx = -b / 2a
✓ Correct Answer: A — x = (-b ± sqrt(b^2 - 4ac)) / 2a
The quadratic formula is the general solution for any quadratic equation.
