6x(squared)  2xy
________________________ (divided by)
y(squared)  9x(squared)

factor out of the numerator 2x, so that
2x(y3x) is the numerator.
Factor the denominator as the difference of squares. 
How do i do the difference os quares if y and 9x are different.

(a^2b^2)=(ab)(a+b) YOU should have memorized that.
