Quadratic equationUse the slides to change the values of coefficients a, b, and c of the quadratic equation ax² + bx + c. When the parabola does not touch the x-axis, the solutions are imaginary. Otherwise you will get two solutions, that is, two values of x, namely, x1 and x2. When the curve touches the x-axis, there are two solutions of the same value.
