HI, here is the proof :
Remainder theorem says that -
if a polynomial f(x) is divided by (x-a) the remainder = f(a)
Proof :
By division algorithm for f(x) and (x-a) there exists a unique quotient q(x) and a constant remainder say c,such that
f(x) = (x-a)* q(x) + c
on putting x = a,
f(a) = (a-a) * q(x) + c = 0 * q(x) + c = c
hence , remainder = f(a)
thus when a polynomial f(x) is divided by (x-a) the remainder = f(a) = remainder theorem
