, divide both sides by 6,





One of the binomials of the denominator must be positive while the other is negative. The critical points to test separating the intervals are at x=-4 and x=1. Pick any value for x in each of these three intervals and test:

(-infinity, -4)
(-4, +1)
(+1, infinity)

The numerator is negative. You must choose the intervals which make the entire denominator itself be negative.
