Does it help to know that 125 is the cube of 5? And that a^3 is also a perfect cube? Have you heard the phrase, "sum of two cubes" before in your current course material/ If so, how do you factor the sum of two cubes?

You might want to look up "special products and factors" in your textbook or other learning materials. You'll almost surely find the formula in question if you do that.
