When we are solving by graphing, the x intercepts are where the equation is true. So lets graph this. http://www.wolframalpha.com/input/?i=graph+-18x%5E3%2B20x%5E2-5x%3D0
OpenStudy (anonymous):
The answers are the x - intercepts so x = 0,0.375, and 0.725 Tag me if these are not in the choices or if you cant just submit that graph.

If this is correct please give me a medal.
OpenStudy (jmark):
Find the intercepts and the maximum and minimum values.
