WebNov 1, 2024 · How to: Solve a Polynomial Inequality. Step 1: Rewrite the inequality so there is a zero on the right side of the inequality. The expression on the left side designate as f(x). Step 2 : Find the critical numbers. Critical numbers for polynomial functions are the real number solutions to f(x) = 0. WebFirst, let us clear out the "/3" by multiplying each part by 3. Because we are multiplying by a positive number, the inequalities don't change: −6 < 6−2x < 12. Now subtract 6 from each part: −12 < −2x < 6. Now divide each part by 2 (a positive number, so again the inequalities don't change): −6 < −x < 3. dr michael bone hampton nb https://kadousonline.com
