When simplifying square roots, we give the positive and negative answer if solving an equation that did not originally have a square root. Otherwise, we give only the principal root. Square roots of negative numbers have non-real answers, which is why square roots of variables sometimes include the condition that the variable is greater than zero. Knowledge of math radicals is important when solving quadratic equation problems.

Solving quadratic equations using square roots works best under special circumstances. If your equation does not have a “b” term this technique may be a good one for you to try. Keep in mind that if this technique does not work well with your equation, there are a number of other techniques that can be used instead.
