Help with binomial theorem
Hi guys I need help with these questions
(i) Write out the first few terms in the expansion of (1 + ?) ^ n-1
(ii) By choosing an appropriate value of ? in the expansion above, prove n-1 ^ C1 + n-1 ^ C2... = 2n^ n-1 - 2
(d) In the expansion of (1 + ? + ?? ) the coefficient of ? is zero. By expanding 3
the first few terms or otherwise; what is the value of ??
By the way I couldn’t find any videos explaining these questions, I learn well from videos. If possible could you please link me some videos about these topics of the binomial questions
