If you are looking at a graph of a quadratic equation, how do you determine where the solutions are?

Answer by  esteban (1334)

In the graph of a quadratic equation, the points where the parabola crosses the x-axis are the solutions to the equation. If the parabola crosses the x-axis at two points, there are two solutions. If it touches the x-axis at only one point, then there is one solution. If the parabola never crosses the x-axis, there are no real solutions.

If the quadratic equation is ax²+bx+c = 0 and you look at the graph of y=ax²+bx+c, the solutions occur at x values where graph crosses the x axis
