WebAug 23, 2024 · Method 1: Factoring. f(x) = 0 x2 − x − 2 = 0 x2 − 2x + x − 2 = 0 x(x − 2) + 1(x − 2) = 0 (x + 1)(x − 2) = 0 By the Zero Product Rule, if ab = 0, then a = 0 or b = 0. Hence, x + 1 = 0 or x − 2 = 0 . x + 1 = 0 x − 2 = 0 x = − 1 x = 2 Thus, the x -intercepts are the point ( − 1, 0) and (2, 0). WebIn math, a quadratic equation is a second-order polynomial equation in a single variable. It is written in the form: ax^2 + bx + c = 0 where x is the variable, and a, b, and c are constants, a ≠ 0. How do you know if a quadratic equation has two solutions? A quadratic equation has two solutions if the discriminant b^2 - 4ac is positive.
