\frac{\left(4x-2y\right)\left(9x+9y\right)}{\left(3x+3y\right)\left(2x-y\right)}
Divide \frac{4x-2y}{3x+3y} by \frac{2x-y}{9x+9y} by multiplying \frac{4x-2y}{3x+3y} by the reciprocal of \frac{2x-y}{9x+9y}.
\frac{2\times 9\left(x+y\right)\left(2x-y\right)}{3\left(x+y\right)\left(2x-y\right)}
Factor the expressions that are not already factored.
