Maths - Functions f(x) Polynominal

f(x) is polynomial and is divisible by (x-1). What must be a factor of f(2x+1)?
My calculations:
Sub (2x+1) into (x-1)
= ((2x+1)-1) = 2x
Therefore, f(2x) is the factor of f(2x+1)??
Please show the detail steps - Many Thanks

✔ 最佳答案
Since f(x) is divisible by x-1, f(1) = 0
Hence, f(2(0)+1) = f(1) = 0
Therefore, f(2x+1) is divisible by x.(or 2x, 3x, 4x, ...etc)
