Solving quadratic equations: complex roots (video) Khan Academy
WebWe can use the formula under the radical, b2−4ac, called the discriminant, to determine the number of roots of solutions in a quadratic equation. There are three cases: b2−4ac<0: The equation has 0 real solutions. The graph does not cross the x-axis. b2−4ac=0: The equation has 1 real solution. The graph touches the x-axis at one point. WebA positive discriminant indicates that the quadratic has two distinct real number solutions. A discriminant of zero indicates that the quadratic has a repeated real number solution. … WebMar 31, 2024 · Quadratic Equations with Two Imaginary Solutions. Hi everyone and welcome to MathSux!
