For some reason, if you want to take the square root of both sides, and you get x= +/- 2, because -2 squared is still equal to four. But, according to the original equation, x is only equal to 2. Therefore -2 is an extraneous solution, and squaring both sides of the equation creates them. You can find the square root of a fraction by taking the square roots of the numerator and denominator separately. Watch this video to learn the process. What Is a Square Root? Menu.
