\frac{\left(x^{2}-1\right)\left(x^{2}+7x+6\right)}{\left(2x+2\right)\left(5x-5\right)}
Divide \frac{x^{2}-1}{2x+2} by \frac{5x-5}{x^{2}+7x+6} by multiplying \frac{x^{2}-1}{2x+2} by the reciprocal of \frac{5x-5}{x^{2}+7x+6}.
\frac{\left(x-1\right)\left(x+6\right)\left(x+1\right)^{2}}{2\times 5\left(x-1\right)\left(x+1\right)}
Factor the expressions that are not already factored.
\frac{\left(x+1\right)\left(x+6\right)}{2\times 5}
Cancel out \left(x-1\right)\left(x+1\right) in both numerator and denominator.
\frac{x^{2}+7x+6}{10}
Expand the expression.
