New methods for Solving quadratic Equations and Inequalities

This book presents a thorough review of all traditional courses on solving quadratic equations and inequalities that are being taught in Algebra classes. In addition, it introduces an improved quadratic formula and a new method to solve quadratic equations quickly. It also develops a new method using a double-number-line and a new graphing method for solving combined quadratic inequalities.

The authors are experienced math teachers and tutors who have written two other math books on solving linear equations and on solving trigonometric equations and inequalities (ISBN #14120-66220 and ISBN #14120-73812)
