The"quadraticformula"isthemost preferred method in solving quadratic equations.
Quadratic equations has 1, 2 or no roots at all. When you use the quadratic formula, you can solve a quadratic equation even it has no roots. The other methods cannot find the imaginary roots(if there is) unlike the quadratic formula.
This is the quadratic formula:
To use this, you only need to substitute the values of a, b and c from the standard form of a quadratic equation. Then simplify.
