| Abstract: | The advantages and disadvantages of nonvariable method and coordinate transformation method in the simplification process of quadratic curve equation are discussed; Through the intrinsic link between the two,three new theorems are derived and proved. The new theorem makes the calculation simplify,and makes drawing graphs quick and easy. Finally,examples of simple methods illustrate the specific application of the three theorems in quadratic equation simplification. |
