%28y%5E2%2B9y%2B2%29%28y-8%29 Start with the given expression.


y%5E2%28y-8%29%2B9y%28y-8%29%2B2%28y-8%29 Expand.


Distribute.


y%5E3-8%2Ay%5E2%2B9%2Ay%5E2-72%2Ay%2B2%2Ay-16 Multiply.


y%5E3%2By%5E2-70%2Ay-16 Now combine like terms.


So %28y%5E2%2B9y%2B2%29%28y-8%29 expands to y%5E3%2By%5E2-70%2Ay-16.


In other words, %28y%5E2%2B9y%2B2%29%28y-8%29=y%5E3%2By%5E2-70%2Ay-16.
