1.  Remove the parentheses by changing everything inside the parentheses to its opposite.
2.  Collect the like terms and combine them.

But can you show me how to do this ?

anonymous · Answer

Well, remove the brackets.
you get 5t^4+6t^3+4t-11++9t^4+6t^3-5t^2-3t-8

boobear7411 · Answer

and then ?

mertsj · Answer

Are there any like terms?

anonymous · Answer

14t^4+12t^3+t-19

boobear7411 · Answer

isnt "t" a like term cause 8 numbers have "t" ?

boobear7411 · Answer

Is 14t^4+12t^3+t-19 the answer ?

anonymous · Answer

Wait a sec I forgot a term there

14t^4+12t^3-8t^3+t-19

mertsj · Answer

Like terms must have the same variables and those variables must have the EXACT same exponents.

Thanks.  I am so happy to know that I can now ignore Open Study's Code of Conduct and just post the answers to all the problems I know how to do.

Sorry. But an example and background theory doesn't bite.
