Polynomial Inequalities Worksheet - Web 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. Problems are classified into 2 categories according to the form of polynomials ( factored or standard) of 2 levels of difficulty for each category of polynomial inequalities. 2x4 > 3x3 + 9x2 2x4 − 3x3 − 9x2 > 0. Does the sign chart for any given polynomial or rational function always alternate? X2(2x2 − 3x − 9) = 0. If one side of the inequality is not 0, we need to do some algebra to change it into that form. Obtain zero on one side of the inequality. Web example 3 solve x4+4x3−12x2 ≤ 0 x 4 + 4 x 3 − 12 x 2 ≤ 0. Any inequality that can be put into one of the following forms. Solve polynomial inequalities using boundary value method.

Web begin by finding the critical numbers. Solving a polynomial inequality in factored form. Obtain zero on one side of the inequality. (d) x2 −7x+ 6 ≤ 0; The expression on the left side designate as \(f(x)\).

Determine the sign (positive or negative) of the polynomial as it passes the zero in the rightward direction.
