    You can treat the (3x^2 + 1) as a single term and distribute it.

    yes can you do that for me to show me?

    For example... \[\large \color{blue}{(3x + 4)}(7x^2 -9x +8)\] distribute the "term" on the left (the one in blue) \[\large \large 7x^2\color{blue}{(3x + 4)} -9x\color{blue}{(3x + 4)} +8\color{blue}{(3x + 4)}\] And now, each of these individual terms, you also distribute. It's just repeated distribution.

    It defeats the purpose... besides, giving the answer outright is highly discouraged... much better if you can find it on your own, with some help, of course. Come on, you can do this, it's very similar to what I did, just distribute the entire shebang in the parentheses.... :)

    i think it is 3x^4-6x^3+3x^2-2x+1

    I think it'd be easier to see your mistake if you post your process... that way, if you did make a mistake, it'd be easier to spot where you did it so you don't do it again. :)

    I did solve it, unfortunately, only mentally, so I don't have a complete process Surely you do... don't you? :)

    Nope. Of course I could be wrong... mental calculation is so prone to human error, but i didn't get the same answer.

    @mo913 Looking for answers wont help you at all .Besides our users never give the answers away .They just help you on your problem instead of working out the entire problem .We need the asker to put some effort on solving the question .That will do you wonders in your studies .

    This asker was able to solve a systems problem in detail... so isn't systems a more advanced topic than simple distribution and combining like terms? http://openstudy.com/study#/updates/511abaade4b03d9dd0c343e4
