Solving Quadratic Equations by Taking Square Roots

Students learn to solve quadratic equations by first isolating the squared term, then square rooting both sides of the equation. Note that plus or minus is always used when square rooting both sides of an equation. For example, if x^2 = 25, take the square root of both sides of the equation to get x = plus or minus 5.
