9r2-4s2/9r+6s
It looks like you can factors the numerator
(3r + 2s)(3r - 2s) [This is the factored form of 9r2-4s2]
Put this back into the equation
(3r+2s)(3r-2s)/9r+6s
You can also factor the denominator
3(3r+2s)
Put this back into the equation
(3r+2s)(3r-2s)/3(3r+2s)
You can cancel out the 3r+2s on top and bottom because they are the same they equal 1. Therefore your final answer is
3r-2s over 3
You could go further and say this is...
r-(2/3)s
either one is correct
