The quadratic formula. Many quadratic equations cannot be solved by factoring. This is generally true when the roots, or answers, are not rational numbers. A second method of solving quadratic equations involves the use of the following formula: a, b, and c are taken from the quadratic equation written in its general form of . ax 2 + bx + c = 0
Therefore, when solving quadratic equations by factoring, we must always have the equation in the form " (quadratic expression) equals (zero)" before we make any attempt to solve the quadratic equation by factoring. Returning to the exercise: The Zero Factor Principle tells me that at least one of the factors must be equal to zero.
