solve by taking square roots Follow this guide to learn how to solve quadratic equations using the square root method Isolate all x 2 terms on one side and take the of both sides to calculate x
Extracting roots involves isolating the square and then applying the square root property After applying the square root property you have two linear equations that each can be solved Be sure to simplify all radical expressions and rationalize the denominator if necessary The steps to take to use the Square Root Property to solve a quadratic equation are listed here
