For the following sets describe the set by listing its elements (if infinite use to represent a pattern before/after listing enough of the elements to show how the patter goes):

A = {x Z : 3 < x 5}, so A={ }

B = {3x + 1 | x Z}, B={ }

C = {x R : x^2 x +1 = 0}, C={ }

D = {x R : x^2 + 2 = 0}, D={ }

E = {x Z : x^2 < 15}, E={ }
