\frac{\left(3x+3\right)\left(x^{2}-1\right)}{\left(x-1\right)\left(x^{2}-6x-7\right)}
Divide \frac{3x+3}{x-1} by \frac{x^{2}-6x-7}{x^{2}-1} by multiplying \frac{3x+3}{x-1} by the reciprocal of \frac{x^{2}-6x-7}{x^{2}-1}.
\frac{3\left(x-1\right)\left(x+1\right)^{2}}{\left(x-7\right)\left(x-1\right)\left(x+1\right)}
Factor the expressions that are not already factored.
\frac{3\left(x+1\right)}{x-7}
Cancel out \left(x-1\right)\left(x+1\right) in both numerator and denominator.
\frac{3x+3}{x-7}
