Lesson Summary. The square root property is a property that can be used to solve quadratic equations. It states that if x 2 = c, then x = √c or x = -√c, where c is a number.

How do you solve quadratic equations with square roots?

The Square Root Property is used in solving quadratic equations by eliminating the square exponents to isolate the variable being solved. The formula {eq}x = \pm \sqrt {c} {/eq} gives us two possible answers, the positive and negative of the number that can be multiplied by itself to equal x.

What does the square root property tell us?

The square root property says that if x 2 = c, then or . This can be written as “if x 2 = c, then .” If c is positive, then x has two real answers. If c is negative, then x has two imaginary answers.
