how can this be factored?
27x^3 – 125y^3
the first obvious thing I did was the difference of 2 cubes “factor method” or whatever (lol) and got
(3x – 5y)(9x^2 + 15xy + 25y^2)
is there a way to factor the second set of parentheses out? cuz it sure seems like there’d be. I tried the perfect square trinomial thing but that didn’t work…unless I did it wrong. idk. help would be appreciated. :]

You have done the problem perfectly. You can not factor any further.
