Can you please answer each part of this question correctly. Thank you

This question concerns the field GF(16). The modulus is P(x) = x² + x + 1.
Please answer the following questions about arithmetic in this field.
a) If p(x) = x² + x, what is p¯¹(x) modulo P?
b) lf p(x) = x³ + x² + x, what is p¯¹(x) modulo P?
c) If p(x) = x + 1, what is p¹(x) modulo P?
d) If p(x) = x² + x + 1, what is p¯¹(x) modulo P?
Hint: The inverse of each polynomial appears in another sub-part of the question
