\[\frac{c^{2} + 6c - 9}{c - 2} =\]
\[= \frac{c^{2} - 2c + 8c - 9}{c - 2} =\]
\[= \frac{c(c - 2) + 8c - 9}{c - 2} =\]
\[= \frac{c(c - 2)}{c - 2} + \frac{8c - 9}{c - 2} =\]
\[= c + \frac{8c - 9}{c - 2} =\]
\[= c + \frac{8c - 16 + 7}{c - 2} =\]
\[= c + \frac{8 \cdot (c - 2) + 7}{c - 2} =\]
\[= c + \frac{8(c - 2)}{c - 2} + \frac{7}{c - 2} =\]
\[= c + 8 + \frac{7}{c - 2}\]
