| Abstract: | In this article,the author introduces the definition and the classification of the family of quadric curve,and illustrates its applications with examples in solving the equation of quadric curve,the groups of binary quadratic equation and one variable equation of four times.Thus can make it out that using family of quadric curve to solve a problem can greatly reduce calculation and get twice result with half effort. |
