How to solve a polynomial inequality
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 WebThis precalculus video tutorial provides a basic introduction into solving polynomial inequalities using a sign chart on a number line and expressing the solution as an inequality and using...
How to solve a polynomial inequality
Did you know?
WebI am taking a Pre-Calc class and the process they give to solve Polynomial and Rational inequalities is totally different from both of these ways. They have us find the zeros and take sections of the number line around those. Then create a table and determine which are positive and which are negative. 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. We will learn to solve inequalities once they are of the form where one side of the inequality is a polynomial and the other is 0.
