This math test contains 3 problems: 1) solve the quadratic equation x2 + 3x + 9 = 0 for x, 2) find the set of elements that are in set A={1,2,3,4,5,6} but not in set B={2,4,6,8}, and 3) if sets A and B contain 3 and 6 elements respectively, find the maximum number of elements and that number that can be in their intersection.

1. Test Math
1. Solve for x : x2 + 3x + 9 = 0.
2. If A = {1, 2, 3, 4, 5, 6}, B = {2, 4, 6, 8}, then find A – B
3. Let A and B be two sets containing 3 and 6 elements respectively. Find
the maximum and number of elements in A ∩ B.
