About this document
Solving Inequalities in Algebra by Uziel Rodrigueez is a document available to read on EtoBox.
The document contains 3 examples of determining the sign of expressions involving absolute values. 1) It analyzes the expression |x +6|≥ 1 and determines the intervals where this is true, namely x ≤-7 or x ≥-5. 2) It examines the inequality |x +15|<1 and finds the interval where it is satisfied is -16 < x < -14. 3) It looks at the expression (x +2)(x-5)>0 and identifies the intervals where this is positive as (-∞,-2) or (5, +∞).
