Find the points at which the graphs intersect by solving the equations simultaneously. The answer is 0 and 1. I understand how to get the 0 and 1 but what I don't get is how to solve the equation (x2+x+1). Please see the attached file for the fully formatted problems.
With respect to the ideal I=<2,x> in Z[x] I believe this ideal is maximal because one theorem I have read suggests to me that all maximal ideals of Z[x] are in the form <p, f(x)> where p is prime and f(x) is an element of Z[x] and irreducible mod p. It appears that <2,x> fits this description. Did I understand correc
