Question 65375: Write each expression in simplest form:
4r^2 - 25s^2
------------
2r^2 + 3rs - 20s^2
With this equation I am so lost and confused of how to even start the procedure! Is there any help out there for me? Thank you :-)

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]
