When (a + b + c + d + ... + z)^2 is expanded and simplified, how many different terms will be there?
I think you will have this many terms - somebody should correct me if I'm wrong.
[26 letters of the alphabet]^2
The number of terms of this expansion is calculated as follows:(The exponent of the polynomial)=2) + (number of terms - 1) nCr (the exponent of the polynomial) =[2+26 - 1] nCr 2 =27 nCr 2 =351 terms.
