Graph functions, plot points, visualize algebraic equations, add sliders, animate graphs, and more. The values for a, b and c in the quadratic formula will only work for a quadratic expression set equal to 0.īefore using the quadratic equation to solve 4 x^2-9 x=12, you need to subtract 12 from both sides so that the equation is in the form 4 x^2-9 x-12=0. So our solutions are x 3 and x 2, which means the points ( 2, 0) and ( 3, 0) are where the parabola intersects the x -axis. Explore math with our beautiful, free online graphing calculator.
