# How do you find the product of ((k+6)(k-1))/(k+2)*((k+1)(k+2))/((k+1)(k-1))?

color(red)(k+6
$\frac{\left(k + 6\right) \cancel{{\left(k - 1\right)}^{\textcolor{red}{1}}}}{\cancel{{\left(k + 2\right)}^{\textcolor{red}{1}}}} \cdot \frac{\cancel{{\left(k + 1\right)}^{\textcolor{red}{1}}} \cancel{{\left(k + 2\right)}^{\textcolor{red}{1}}}}{\cancel{{\left(k + 1\right)}^{\textcolor{red}{1}}} \cancel{{\left(k - 1\right)}^{\textcolor{red}{1}}}}$
$\therefore = k + 6$
