anonymous · Answer

use FOIL method , expand the last one and use FOIL method again? :)

anonymous · Answer

give it a try ^_^

anonymous · Answer

lol what?

y expand it?

anonymous · Answer

you need to factor to solve inequalities , in fact in the form it is now you can get the solution in like 30seconds

anonymous · Answer

oh, don't you want to sovle for x?

anonymous · Answer

yeh, can be done in 30 seconds , just its very hard to explain if the asker isnt familiar with how to graph equations with double and triple roots

anonymous · Answer

Im  actually trying to solve for the Domain I suppose. The answer should look something like (-infinity, -9) U (3, infinity) and so on (just an example answer)

anonymous · Answer

answer is x=-9 and the interval -1<=x<=3
