Question: What is the product of
and
?
Answer: ![\frac{3x^2-3}{3x+3}*\frac{x+3}{3x-3}](https://s0.wp.com/latex.php?latex=%5Cfrac%7B3x%5E2-3%7D%7B3x%2B3%7D%2A%5Cfrac%7Bx%2B3%7D%7B3x-3%7D+&bg=ffffff&fg=000&s=3&c=20201002)
![\frac{3x^2+9}{9x+9} \rightarrow \frac{1x^2+3}{3x+3}](https://s0.wp.com/latex.php?latex=%5Cfrac%7B3x%5E2%2B9%7D%7B9x%2B9%7D+%5Crightarrow+%5Cfrac%7B1x%5E2%2B3%7D%7B3x%2B3%7D+&bg=ffffff&fg=000&s=3&c=20201002)
The usual: What does he know, what doesn’t he know, and what would you do next?
