Solution 1

To find the solution set of the inequality (x - 1)(x + 2) > 0, we first find the critical points by setting each factor equal to zero:

x - 1 = 0 => x = 1 x + 2 = 0 => x = -2

These are the points where the expression changes sign. We can test the intervals (-∞, -2), (-2, 1), and (1, ∞) by choos Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
