Rational inequalities worksheets with answers and solutions. 3 describe two methods that can be used to solve a rational equation. Solve the following inequalities. Knowing that the sign of an algebraic expression changes at its zeros of odd multiplicity solving an inequality may be reduced to finding the sign of an algebraic expression within intervals defined by the zeros of the expression in question.

Be sure to exclude any solution that would produce a denominator of zero. Determine all values that make the denominator zero 4. Draw a number line and mark all the solutions and critical values from steps 2 and 3 5.

One approach for solving the inequality. 9 6 solving rational equations 571 1 give an example of a rational equation that can be solved using cross multiplication. 3 as and as.

Solve the equation 3. Write the inequality as an equation 2. Linear inequality worksheets contain graphing inequalities writing inequality from the graph solving one step two step and multi step inequalities graphing solutions solving and graphing compound inequalities absolute value inequalities and more.

2 a student solved the equation x º 2 3 x º x 3 and got the solutions 2 and 3. The printable exercises cater to the learning requirements of students in grade 6 through. To solve a rational equation first multiply each side by the least common denominator of all of the denominators.

You must remember that the zeros of the denominator make. Here is a set of practice problems to accompany the rational inequalities section of the solving equations and inequalities chapter of the notes for paul dawkins algebra course at lamar university. The key approach in solving rational inequalities relies on finding the critical values of the rational expression which divide the number line into distinct open intervals.

Explain how you know. Graph the rational expression 1 because and a divide by is undefined in the real number system there is a vertical asymptote where.
