| Abstract: | The generalized quardratic algebraic inequality is considered in this paper. The generalized quardratic algebraic inequality is obtained by using the method of completing the square and solution of the cubic algebraic equation. Many results of this kind of inequalities can be deduced as special cases from the results in this paper. |
