[疑難] Somebody can help

I don't know how to solve the problem, could U help?!
CRC Computation
Consider a message represented by some polynomial G(x), and a generating polynomial P(x).
Let G(x) represent the binary message 110010, and let P(x) = x3 + x2 + 1; (binary 1101).
The polynomial P(x) will be used to generate a (3-bit) CRC called C(x) which will be appended to G(x).
Note that P(x) is prime.
110010 CRC
The polynomial P(x) defines the CRC bits.
