You can put this solution on YOUR website!

y%5E2-5y=0

y%28y-5%29=0 Factor the left side (note: if you need help with factoring, check out this solver)



Now set each factor equal to zero:

y=0 or y-5=0

y=0 or y=5 Now solve for x in each case


So our solutions are y=0 or y=5


Notice if we graph y=y%5E2-5y we get

+graph%28500%2C500%2C-10%2C10%2C-10%2C10%2C+x%5E2-5x%29+

and we can see that the graph has roots at x=0 and x=5, so this verifies our answer.
