simplify (6n+6)/(n+9)*(n^2+6n-27)/(6n+6)

simplify

\frac{6 n + 6}{n + 9} \cdot \frac{n ^{2} + 6 n - 27}{6 n + 6}

n - 3

Solution steps

\frac{6 n + 6}{n + 9} \cdot \frac{n ^{2} + 6 n - 27}{6 n + 6}

Cross-cancel common factor:

6 n + 6

= \frac{n ^{2} + 6 n - 27}{n + 9}

Cancel

\frac{n ^{2} + 6 n - 27}{n + 9} : n - 3

= n - 3

2 - 3 (x + 5) = 5 x - 13

\frac{2 x - 7}{4} \leq \frac{1}{5}

(\frac{1}{4 ab})^{- 2}

\frac{x + 1}{4} - \frac{1}{6} = \frac{2 - x}{3}
