To solve a rational inequality, we factor the numerator and the denominator into irreducible factors. The cut points are the real _____ of the numerator and the real ________ of the denominator. Then we find the intervals determined by the _________, and we use test pointsto find the sign of the rational function on each interval.
Let
Fill in the diagram below to find the intervals on which
Sign of
From the diagram, we see than on the intervals _______, ________ and ________.
