You can put this solution on YOUR website!
If you graph the function, you will see the roots clearly.
Unfortunately due to the limitations of this graphing utility, they don't all show up.
x=2, double root
x=4
x=5
x=7, double root
x=8
Verify that they are indeed roots by plugging them into the equation.
