Question

multiply and simplify:

(3x^2+1) (x^2-2x+1) - (x^2+4x)

Answer 1

Is this one whole equation?

Answer 2

yes
distribute

Answer 3

i am just confused how to to distribute my exponents

Answer 4

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

Answer 5

yes can you do that for me to show me?

Answer 6

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.

Answer 7

can u show me my problem...as the example?

Answer 8

like what would the asnwer be?

Answer 9

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.... :)

Answer 10

i am confused how to distribute exponents

Answer 11

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

Answer 12

would that be it?

Answer 13

I actually don't know yet... I haven't tried it on the problem itself... :D

Answer 14

can u please and let me know? that would help a lot

Answer 15

okay done :)

Answer 16

great! and if u didnt get that post what u got so i can see my mistake

Answer 17

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.
:)

Answer 18

ok well just post what u get cause i cant post every step

Answer 19

for me it will be easier if u solve it and i can see where I messed up

Answer 20

or even i did at all. i could be right

Answer 21

please just solve it and i can compare my answer to urs

Answer 22

bc i could be right

Answer 23

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

Answer 24

ok...so did u get the same thing as I did?

Answer 25

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

Answer 26

what was ur answer (final) u got?

Answer 27

That's why process is important.

Answer 28

what was urur final answer?

Answer 29

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

Answer 36

@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 .

Answer 37

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?
