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

  • anonymous
yes can you do that for me to show me?
terenzreignz
  • terenzreignz
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.

can u show me my problem...as the example?
anonymous
  • anonymous
like what would the asnwer be?
terenzreignz
  • terenzreignz
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 am confused how to distribute exponents
anonymous
  • anonymous
i think it is 3x^4-6x^3+3x^2-2x+1
anonymous
  • anonymous
would that be it?
terenzreignz
  • terenzreignz
I actually don't know yet... I haven't tried it on the problem itself... :D
anonymous
  • anonymous
can u please and let me know? that would help a lot
terenzreignz
  • terenzreignz
okay done :)
anonymous
  • anonymous
great! and if u didnt get that post what u got so i can see my mistake
terenzreignz
  • terenzreignz
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. :)
anonymous
  • anonymous
ok well just post what u get cause i cant post every step
anonymous
  • anonymous
for me it will be easier if u solve it and i can see where I messed up
anonymous
  • anonymous

anonymous
  • anonymous

anonymous
  • anonymous

terenzreignz
  • terenzreignz
I did solve it, unfortunately, only mentally, so I don't have a complete process Surely you do... don't you? :)
anonymous
  • anonymous
ok...so did u get the same thing as I did?
terenzreignz
  • terenzreignz
Nope. Of course I could be wrong... mental calculation is so prone to human error, but i didn't get the same answer.
anonymous
  • anonymous

terenzreignz
  • terenzreignz
That's why process is important.
anonymous
  • anonymous

terenzreignz
  • terenzreignz
:) I'm withholding it until you show me your process... sorry, giving the final answer is highly discouraged... check the Code of Conduct...

@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
