need someone to check my math problem

[Brandi]

This is only a homework problem which counts as a few measly points of extra credit at the end of the course if we turn it in (and it doesn't really matter if it's necessarily right or wrong, he just wants to see us working it out). I just want to see if the answer I came up with is right. Our book only answers odd numbers and this one is even so I have no way to check it.

Anyone who is good with polynomials can help I have no idea if or how to enter in exponents so I'm just going to use the ^ then the number after it is the exponent. So, for 6 cubed, I will put 6^3 and for say 9 to the 8th power I will write 9^8 or v to the sixth power I'll put v^6
I hope that doesn't confuse anyone.


(tu^2v-4t^2u^2v+9t^3uv+3tv)+(3t^2u^2+2tv-t^3)-(4t^2u^2v+3tv+2tu^2v)-(6t^3uv+2tv)


My answer is
-8t^2u^2v+3t^3uv+3t^2u^2-tu^2v-3tv-3t

but I honestly don't think that's right. Ugh. I just got done doing 100 problems like this and looking at the letters and numbers are frying my brain

jeez, all those ^s are making my eyes go funny!

Man, I wish I could help you...

[Brandi]

I know! I am sorry. There is no way to write exponents on a regular keyboard though is there? Not with ALT or anything? I wish I could.

[April]

give me a minute

[Brandi]

hubby checked and said the -3tv is wrong b/c they cancel each other out. My addition was wrong, I think.

Thank you for helping April

[April]

I got something different


-8t^2u^2v+3t^3uv+3t^2u^2-tu^2v-t^3

I'll try again

Edited because I typed the last one wrong, but I got the same answer both times

[Brandi]

these little damn ^^^ things make it hard huh? I wish there was a way to write exponents. grrr.

Thank you for helping though

[April]

I edited my answer if you already looked at it

[April]

yes those ^^^^^ take forever to write
