Purpose To implify curved surface of second degree and to give out an exact coordinate expression, at the same time solve some polynomials factor decomposition. Method Adopted the theories of the matrix algebra. Result Obtained formulas of curved surface of second degree simplified with some conclusion related of polynomials factor decomposition. Conclusion It is feasible to simplified curved surface of second degree and solved some polynomials factor decomposition by the theories of the matrix algebra. This kind of method is workable. This kind of method is a kind of new method that curved surface of second degree is simplified.
