i know what they are i just need help with solving the problem. i dont understand it. and im taking an online course

OpenStudy (amistre64):

well, pascals triangle gives us the coefficients of the expansion the rest is just working the exponents in the right order i spose give it a shot, let me see what you come up

OpenStudy (amistre64):

.. having connection issues

OpenStudy (anonymous):

okay. thank you

OpenStudy (amistre64):

binomial thrm gives us: \[(a+b)^n=\sum_{k=0}^{n}\binom{n}{k}a^{n-k}~b^k\]
