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.
