Solve for the inequality below. be sure to show the factorization of the polynomial and the work it took to get there (4 pts), how you found the boundary points (2 pts), your work for testing your intervals (2 pts), and your final answer in interval notation (2 pts).

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

i think the answer is b.
