Inequality Solver
Type an inequality and see how it is solved: critical values, a test in every region, and the answer drawn on a number line.
What you can do
- Solve linear, quadratic and rational inequalities exactly, including surd answers
- Get the answer in plain form, interval notation and set notation
- See a sign chart for every factor, and a number line with open and closed circles
- Keeps values that make the bottom zero out of the answer
- Practise with random questions and worked solutions
