One way to solve a quadratic is to use square root. Steps:
- Factor a quadratic so that it is in the form ( can be determined by completing the square)
- Take the square root of both sides, so
- If y is 0, the square root is zero. In this case, there will only be one solution instead of two.
- Solve for x
