To solve a polynomial inequality, we factor the polynomial into irreducible factors and find all the real _______of the polynomial. Then we find the intervals determined by the real____
and use test points in each interval to find the sign of the polynomial on that interval. Let
Fill in the diagram below to find the intervals on which
From the diagram above we see that
