The binomial expansion of is ...
(1)
At this point the research of the value of a is a pure algebraic practice ...
Kind regards
when ( 1+2x) (1+Ax)^2/3 is expanded in asending powers of x the coefficient of the term n x is zero
1) find the values of A
2) when A has this value find the term in x^3 in the expansion of
( 1+2x) (1+Ax)^2/3 simplifly the coeeficient
