You can put this solution on YOUR website! 9 - x square over y square divided by 3 - x over y
------------------------------------------------------
[(9-x^2)/y^2] / [(3-x)/y]
-------
Invert the denominator and multiply:
[(9-x^2)/y^2] * [y/(3-x)]
-----------
Cancel factors common to numerator and denominator to get:
(3+x)/y
