Inequality Calculator

This calculator will solve the linear, quadratic, polynomial, rational and absolute value inequalities. It can handle compound inequalities and systems of inequalities as well.

To graph inequalities, use the graphing calculator.

Enter inequalities:
Enter compound inequalities as 4<2x+5<=7, separate inequalities by commas.
For absolute values, use abs: 2<=abs(3x-4)<5 will be treated as 2<=|3x-4|<5.

If the calculator did not compute something or you have identified an error, or you have a suggestion/feedback, please write it in the comments below.

Your input: solve $$2 < \left|{x - 1}\right| \leq 4$$$Answer Answer: $$\left[-3, -1\right) \cup \left(3, 5\right]$$$

Approximate Form: $$\left[-3, -1\right) \cup \left(3, 5\right]$$\$
