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.**
