How to solve a polynomial inequality
WebAs has been noted, the easiest way to solve a polynomial inequality f ( x) < 0 (or f ( x) > 0) is to find the roots of the polynomial f, and then form a sign chart. I would like to mention the reason why sign charts work.

WebMany simple inequalities can be solved by adding, subtracting, multiplying or dividing both sides until you are left with the variable on its own. But these things will change direction of the inequality: Multiplying or dividing both sides by a negative number Swapping left and right hand sides WebLearn how to solve polynomial inequalities algebraically using a number line. We go through 3 examples illustrating how to use factoring, sign analysis, writing the solution in …
WebOct 6, 2024 · Solve the given inequality. x2 − 2 x − 3 > 0 In this problem, we have the same asymptote as the previous two problems: x = 3. However, in this inequality, there are two roots, because there are two x values that make the numerator equal zero. x2 − 2 = 0 means that x2 = 2 and x = ± √2 ≈ ± 1.414 We can see these roots on the graph. WebBut you will need to be able to solve every other (linear) factor. Find the solution: (x − 5)2 (x − 1) (x + 3) ≤ 0. For this polynomial inequality, I'm looking for where the graph is below the axis; that is, where the polynomial is less than zero. And since this is an "or equal to" inequality, I'll be including the interval endpoints, the ...
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. 2.)...
WebSolving Polynomial Inequalities Note: This material is to supplement Section 3.6. Unlike linear inequalities, polynomial inequalities cannot always be solved with just algebra, and other techniques will need to be used.
