Quadratic equations are of the form ax + bx + c = 0, where a 0 Quadratics may have two, one, or zero real solutions . 1. Completing the SquareIf the quadratic equation is of the form ax + bx + c = 0, where a 0 and the quadratic expression is not factorable, try completing the square. Example: x + 6x  11 = 0 **Important: If a 1, divide all terms by “a” before proceeding to the next steps.
2. Quadratic FormulaAny quadratic equation of the form ax + bx + c = 0, where a 0 can be solved for both real and imaginary solutions using the quadratic formula: Example: x + 6x  11 = 0 (a = 1, b = 6, c = 11) Substitute values into the quadratic formula: Simplify the radical This is the final simplified EXACT answer.
