\frac{\frac{9x}{\left(x^{2}+x-2\right)\left(x+2\right)}}{\frac{9x}{\left(x^{2}+x-2\right)\left(x+2\right)}}
Multiply \frac{9}{x^{2}+x-2} times \frac{x}{x+2} by multiplying numerator times numerator and denominator times denominator.
\frac{9x\left(x^{2}+x-2\right)\left(x+2\right)}{\left(x^{2}+x-2\right)\left(x+2\right)\times 9x}
Divide \frac{9x}{\left(x^{2}+x-2\right)\left(x+2\right)} by \frac{9x}{\left(x^{2}+x-2\right)\left(x+2\right)} by multiplying \frac{9x}{\left(x^{2}+x-2\right)\left(x+2\right)} by the reciprocal of \frac{9x}{\left(x^{2}+x-2\right)\left(x+2\right)}.
