Question 846143: Use the sum-of-two-cubes pattern to factor the following.
(125x^3+27y^3)
I've got: (5)^3+(3)^3
This is the answer I got and Webassign told me it wasn't correct:
(5x+3y)(5x^2-15xy+9y^2)
Thank you for your help!

It should be 25x%5E2 and not 5x%5E2 in your right hand side term.
125x%5E3%2B27y%5E3=%285x%2B3y%29%2825x%5E2-15xy%2B9y%5E2%29
