WebTo solve polynomial inequalities, follow the steps below: 1.) Manipulate the inequality so you'll have a polynomial on one side of the inequality symbol and zero on the other side. WebSolving Polynomial Inequalities. A polynomial inequality A mathematical statement that relates a polynomial expression as either less than or greater than another. is a mathematical statement that relates a polynomial expression as either less than or greater than another. We can use sign charts to solve polynomial inequalities with one variable.
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.

Write the inequality so that a polynomial or rational expression f is on the left side and zero is on the right side in one of the following forms: f (x) > 0 f (x) ≥ 0 f (x) < 0 f (x) 0 For rational expressions, be sure that the left side is … WebSolve a rational inequality. Step 1. Write the inequality as one quotient on the left and zero on the right. Step 2. Determine the critical points–the points where the rational expression will be zero or undefined. Step 3. Use the critical points to divide the number line into intervals. Step 4.
