SUMMARY
The inequality x^2 + x < 0 can be solved by factoring the expression into x(x + 1) < 0. The critical points are x = 0 and x = -1, which divide the number line into intervals. Testing these intervals reveals that the solution set is (-1, 0), where the inequality holds true. This method effectively demonstrates the process of solving quadratic inequalities.
