Best ResponseYou've already chosen the best response.0I guess I understand how to write it all out just not how to simplify it correctly to get a condensed answer like the ones they provide

Best ResponseYou've already chosen the best response.0http://www.wtamu.edu/academic/anns/mps/math/mathlab/col_algebra/col_alg_tut54_bi_theor.htm Look at example 8... if you have problems I'll do it out for you

Best ResponseYou've already chosen the best response.0Ha ha I'm on that site right now trying to work it out lol Does it matter though if it's rth term or nth term?

Best ResponseYou've already chosen the best response.0doesn't matter coz thats just a variable

Best ResponseYou've already chosen the best response.0well if you are following the site, the rth term is 4, the nth term is 10

Best ResponseYou've already chosen the best response.0\[{10 \choose 4 }=210\] 4th term is \[210 x^6 (5y)^4\]

Best ResponseYou've already chosen the best response.0of course i could be wrong. the 'n=4' is not clear.

Best ResponseYou've already chosen the best response.0wow ok the answer I got isn't even close to any of these.... I got 100800x^7125y^3....not quite sure what id id wrong

Best ResponseYou've already chosen the best response.1the 4th term is 120 x^7 y^3 as a standard... tehn you have to account for the coeefs in the original problem....namely the +5 attached to the y

Best ResponseYou've already chosen the best response.0ok the problem is: Find the specified nth term in the expansion of the binomial. (Write the expansion in descending powers of x.) (x  2y)^12, n = 6 I got 760x^7y^5 which is definitly not one of my answer choices....

Best ResponseYou've already chosen the best response.1at 6 eh 12 11 10 9 8 7 x^6 y^6 is gonne be the variable answers

Best ResponseYou've already chosen the best response.1you got any with ony an x^6 y^6 as an asnswer?

Best ResponseYou've already chosen the best response.0oh it's cause I used the 12 instead of the six let me try it again....

Best ResponseYou've already chosen the best response.0oh ok so I was right now....idk how I got the 760.... cause that's nowhere close to their choices

Best ResponseYou've already chosen the best response.1lol..... which choice has the right x and y parts?

Best ResponseYou've already chosen the best response.1well lets play detective shall we :) is the  part correct? 2^5 = a negative right? so i believe the negative is right... if its got the right x and y parts, then its a sure shot

Best ResponseYou've already chosen the best response.0Do you know the binomial theorem?! It's quite easy to do it using this theorem.

Best ResponseYou've already chosen the best response.0ya it's weird I can find the x and y parts but the number before I somehow lkeep messing up
