%283a%2B2%29%28a%5E2-3a%2B2%29 Start with the given expression.


3a%28a%5E2-3a%2B2%29%2B2%28a%5E2-3a%2B2%29 Expand.


Distribute.


3%2Aa%5E3-9%2Aa%5E2%2B6%2Aa%2B2%2Aa%5E2-6%2Aa%2B4 Multiply.


3%2Aa%5E3-7%2Aa%5E2%2B4 Now combine like terms.


So %283a%2B2%29%28a%5E2-3a%2B2%29 expands to 3%2Aa%5E3-7%2Aa%5E2%2B4.


In other words, %283a%2B2%29%28a%5E2-3a%2B2%29=3%2Aa%5E3-7%2Aa%5E2%2B4.
