用配方法证明一个推广的二次不等式

A Generalized Quardratic Inequality Proved with the Method of Completing the Square

利用配方法和三次代数方程的求根公式,得到了一个推广的二次代数不等式。很多类型的不等式都是这个推广的二次代数不等式的特例。

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.
