When using the quadratic formula, you should be aware of three possibilities. These three possibilities are distinguished by a part of the formula called the discriminant. Thediscriminantis the value under the radical sign,b2– 4ac. A quadratic equation with real numbers as coefficients can have ...
Completing the square formula In order to solve a quadratic equation by completing the square, follow these steps: If the leading coefficient of your quadratic equation is not 11 (i.e., if the polynomial is not monic), then divide both sides by aa. Assume we have the expression x2+bx+...
