Question 668832: I solved the inequality x^2-11x+30 > 0. My notation is (neg. infinity, 5) or (6, pos. infinity). I say "or" because that's my textbook gives the answer. However, my teacher corrects my work and put "and". Which is correct? Or should I put the union symbol?
(-00, 5) U (6, 00)
"00" stands for infinity.
