  2. Next, we need to factor the quadratic . We look for two numbers that multiply to and add to . The numbers and work:
  3. So the inequality becomes:
  4. Now we find the critical points by setting the expression equal to zero:
  5. The critical points are . We will test intervals defined by these points: , , , and .
  6. Choose a test point from each interval:
    • For (e.g., ):
    • For (e.g., ):
    • For (e.g., ):
    • For (e.g., ):
  7. From the tests, the intervals where the inequality holds are and .
Thus, the solution in interval notation is:
