![]() Its shape is a parabola that opens upwards or downwards depending upon the value of a. Its general form is given by, ax 2 + bx + c 0. A quadratic equation is a second-degree polynomial. Since the discriminant is 0, there is 1 real solution to the equation. Let’s look at some approaches for solving the quadratic equations. Since the discriminant is negative, there are 2 complex solutions to the equation.Ī = 9, b = −6, c = 1 a = 9, b = −6, c = 1 Since the discriminant is positive, there are 2 real solutions to the equation.Ī = 5, b = 1, c = 4 a = 5, b = 1, c = 4 The equation is in standard form, identify a, b, and c.Ī = 3, b = 7, c = −9 a = 3, b = 7, c = −9 To determine the number of solutions of each quadratic equation, we will look at its discriminant. The left side is a perfect square, factor it.Īdd − b 2 a − b 2 a to both sides of the equation.ĭetermine the number of solutions to each quadratic equation.
