Quadratic Equations · Factoring & Discriminant
by Anonymous
Set two roots, expand (x−r₁)(x−r₂)=0 and watch the discriminant b²−4ac tell how many real roots meet the parabola's x-intercepts.

About this app
A middle-school interactive quadratic equation explorer that connects factoring, the discriminant, roots, and parabola x-intercepts. Adjust two roots to see how expansion changes the coefficients, change a, b, and c to observe how D = b²−4ac determines the number of real roots, and solve four multiple-choice challenges.
Use cases
