To solve a we factor the numerator and the denominator into irreducible factors. The cut points are the real zeros of the numerator and the real zeros denominator. Then we find the intervals determined by the cut points, and we use test points to find the sign of the rational function on each interval.
Let
Set the numerator equal to zero and solve for x.
Set the denominator equal to zero and solve for x.
Therefore, the cut points are
From the diagram, we see that
