\frac{\left(x^{2}-1\right)\left(12-6x\right)}{\left(x-2\right)\left(x+1\right)}
Divide \frac{x^{2}-1}{x-2} by \frac{x+1}{12-6x} by multiplying \frac{x^{2}-1}{x-2} by the reciprocal of \frac{x+1}{12-6x}.
\frac{6\left(x-1\right)\left(x+1\right)\left(-x+2\right)}{\left(x-2\right)\left(x+1\right)}
Factor the expressions that are not already factored.
