(1 point) This question concerns the field GF(16). The modulus is P(x) = x + x + 1. Please answer the following questions about arithmetic in this field. a) If p(x) = x and g(x) = x, what is p(x) + g(x) modulo P? x^2+x b) lt p(x) = x + 1 and g(x) = x + x + 1, what is p(x) + f(x) modulo P? c) If p(x) = x + x + 1 and g(x) = x +x? + 1, what is p(x) q(x) modulo P? d) If p(x) = x + x + x + 1 and g(x) = x + 1, what is p(x) g(x) modulo P
