Let f(x) = x³ + x² - 4x − 4, g(x) = x¹ + 3x³ + 5x² +9x + 6 and consider the ideal I = (f(x), g(x)) generated by f and g in the rings R[x] and Z/7Z[x]. Since these are both principal ideal rings, we must have I = (h(x)) for some h(x). Find h(x) in each case, using a monic polynomial and using coefficients in the range 0 to 6 for Z/7Z. 1. In R[x], we have I = (2 2. In Z/7Z[x], we have I = (6
