Quadratic Formula:
- Write the quadratic equation in standard form:
- $$ax^{2} + bx + c = 0$$
- Record the needed values:
- a is the coefficient of x2
- b is the coefficient of x
- c is the constant term
- Substitute the known values for a, b, and c into the quadratic formula:
- $$x = \frac{-b \pm \sqrt{b^{2} - 4ac}}{2a}$$
