I'm assuming it reads

%282a%5E2-3a%2B5%29-%283a%5E2%2B8a-4%29

right?


%282a%5E2-3a%2B5%29-%283a%5E2%2B8a-4%29 Start with the given equation


2a%5E2-3a%2B5-3a%5E2-8a%2B4 Distribute the negative


%282a%5E2-3a%5E2%29%2B%28-3a-8a%29%2B%285%2B4%29 Group like terms

-a%5E2-11a%2B9 Combine like terms



So %282a%5E2-3a%2B5%29-%283a%5E2%2B8a-4%29 simplifies to -a%5E2-11a%2B9
