Calculate the solution of the quadratic equation

as the root or fraction.
You can freely enter the coefficients a, b, and c for calculation.
Draw a graph of the quadratic function using the entered values. (following)
The graph can be enlarged, reduced, moved, and scaled to make it easier to get an image of the formula.

Enter the coefficients a, b, c and the answer will be output.

 

The graph is drawn.

You can change the grid spacing and the scale by entering the numbers.

 

The intersection with the x-axis of the graph (a straight line with y = 0) is the solution to the equation

 

When there is one solution, the graph intersects the x-axis at one place.
