\frac{\left(x^{2}+3x-18\right)\left(x+4\right)}{\left(x+4\right)\left(x^{2}+7x+6\right)}
Divide \frac{x^{2}+3x-18}{x+4} by \frac{x^{2}+7x+6}{x+4} by multiplying \frac{x^{2}+3x-18}{x+4} by the reciprocal of \frac{x^{2}+7x+6}{x+4}.
\frac{x^{2}+3x-18}{x^{2}+7x+6}
Cancel out x+4 in both numerator and denominator.
\frac{\left(x-3\right)\left(x+6\right)}{\left(x+1\right)\left(x+6\right)}
Factor the expressions that are not already factored.
\frac{x-3}{x+1}
Cancel out x+6 in both numerator and denominator.
