\frac{\left(2a^{2}+5ab+2b^{2}\right)\left(a-2b\right)}{\left(a^{2}-ab-2b^{2}\right)\left(a+2b\right)}
Divide \frac{2a^{2}+5ab+2b^{2}}{a^{2}-ab-2b^{2}} by \frac{a+2b}{a-2b} by multiplying \frac{2a^{2}+5ab+2b^{2}}{a^{2}-ab-2b^{2}} by the reciprocal of \frac{a+2b}{a-2b}.
\frac{\left(a-2b\right)\left(a+2b\right)\left(2a+b\right)}{\left(a+b\right)\left(a-2b\right)\left(a+2b\right)}
Factor the expressions that are not already factored.
\frac{2a+b}{a+b}
Cancel out \left(a-2b\right)\left(a+2b\right) in both numerator and denominator.
