Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
4r^2 - 25s^2
------------
2r^2 + 3rs - 20s^2
===========================
Factor where you can, as follows:
[(2r-5s)(2r+5s)]/[2r-5s)(r+4s)]
Cancel the factor that is common to the numerator and denominator:
=[2r+5s]/[r+4s]
