Hi, how would I start this question?
Given that the expansion of (1+cx)n begins 1+24x+264x2….. find c and n.
I'm really not sure how to begin. I can do questions asking me to expand the bracket, but I don't really know how to do it the other way around. I normally find the coefficients by using the nCr button on my calculator or pascals triangle for the small ones.
Thanks for your help in advance!
