Advanced inequalities are not about memorizing more symbols. They are about tracking regions of possible answers. An equation usually asks, "Which value makes this exactly …
Open trial session →Interval notation is a compact way to write solution sets. Symbols:. Parentheses \(( \ )\): endpoint is not included. Brackets \([ \ ]\): endpoint is …

Harder linear inequalities often include parentheses on both sides, negative coefficients, or variables on both sides. Example 1:. Distribute and combine:. Add 7 and divide:. …
Open trial session →Compound inequalities combine two conditions. AND means overlap:. The value must satisfy both sides. OR means union:. Either region works. Example 1:. Subtract 6 from …

A sign chart tracks whether each factor is positive or negative in each interval. Example:. Critical points:. They split the number line:. \((-\infty,-2)\). \((-2,1)\). \((1,4)\). …
Open trial session →A rational inequality has a variable in a denominator. Denominators create excluded values. Example 1:. Critical values:. Numerator zero: \(x=3\). Denominator zero: \(x=-2\), excluded. Test …
