How do you graph quadratics? I know the long way of solving them, but I have to do 16 problems and that would take forever... so how would I use my graphing calculator to solve? The first problem is x(x-7) = 0 as an example.
You could plot y = the quadratic, and see where it crosses the x-axis (where y = 0). For example:
though, in the case of this example it is easy to see from the form of the equation that the roots are 0 and 7.
