Multiply the polynomials P1 = (x5 + x2 + x) by P2 = (x7 + x4 + x3 + x2 + x) in GF(28) with irreducible polynomial (x8 + x4 + x3 + x + 1). The result is

Multiply the polynomials P1 = (x5 + x2 + x) by P2 = (x7 + x4 + x3 + x2 + x) in GF(28) with irreducible polynomial (x8 + x4 + x3 + x + 1). The result is Correct Answer x5+ x3+ x2+x+1

On performing polynomial multiplication we get with respect to modulus (x8 + x4 + x3 + x + 1) we get x5+ x3+ x2+x+1.
