1 Αυγ 2015 · The easiest way to solve this quadratic equation is to isolate x2 on one side of the equation, then take the square root of both sides. To do that, add 4 to both sides of the equation. x2 − 4 + 4 = 4. x2 = 4. Taking the square roots of both sides of the equation will get you. √(x2) = √4. = ± 2 = {x1 = −2 x2 = 2.
