Question

Problem 40. Solve the inequality. Express the solution set in interval notation. (More examples in section 3.6) 12x^3 + 10x^2 > 0 Step 1. Write the inequality in its corresponding standard equation form. Step 2. Identify critical points (or zeros) by solving the equation. Steps 3 & 4. Mark all critical points on the number line and in each section select a value for x in that section (different from critical points) and plug it into the original inequality to determine whether it makes the inequality true or not.
