Find the coefficient of x2 in the polynomial, p (x) = 2 x - 1.0​

Answer 1

Answer:

(1+x+x2+x3+...+x100)3

Coefficient of xn in an expression (x1+x2+...+xm) can be given as C(n+m−1,n).

Here, n=100,m=3.

∴ Coefficient of 100th term in given expression =C(100+3−1,100)=C(102,100)=C(102,2).

so, option C will be the correct option.
