Solving systems of polynomial inequalities with algebraic geometry methods Laura Menini, Corrado Possieriyand Antonio Tornambèz Dipartimento di Ingegneria Civile e …... That means that the only place the inequality can change is at an x-intercept, a zero, a root, a solution. The key then, to finding the solution set for a polynomial inequality, is to find the zeros of the inequality (pretend it was an equation), putting them on the number line, and picking a test point in each region.

Solving systems of polynomial inequalities with algebraic geometry methods Laura Menini, Corrado Possieriyand Antonio Tornambèz Dipartimento di Ingegneria Civile e …... Quadratic inequalities are one type of polynomial inequality. Other examples of polynomial inequalities are-2x 4 + x 2 - 3 7, (2/3)x + 4 ≥ 0, and 4x 3 - 2x 2 > 5x + 7. When the inequality symbol in a polynomial inequality is replaced with an equals sign, a related equation is formed. Polynomial inequalities can be easily solved once the related equation has been solved. EXAMPLE 1 Solve: x 3 - x > 0.

## How To Solve Polynomial Inequalities Algebraically

Therefore, solving polynomial inequalities amounts to finding the zeroes of the function and determining the sign of each interval. However, finding the sign of each interval is also straight-forward since every point in any given interval will have the same sign. Therefore, one just has to choose a test-point for each interval to determine the sign of the entire interval (which in turn solves inequality).

- Polynomial inequalities may be solved graphically by determining the x-intercepts and then using the graph to determine the intervals that satisfy the inequality. Factoring inequalities can be solved algebraically by:
- This approach to solving equations is based on the fact that if the product of two quantities is zero, then at least one of the quantities must be zero. In other words, if a*b = 0, then either a = 0, or b = 0, or both. For more on factoring polynomials, see the review section
- Rational Functions are just those with polynomials Solving Rational Inequalities Algebraically Using a Sign Chart. The easiest way to solve rational inequalities algebraically is using the sign chart method, which we saw here in the Quadratic Inequalities Section Method. A sign chart or sign pattern is simply a number line that is separated into partitions (or intervals or regions), with
