代数方程是初等数学的中心课题之一。良好的解方程训练是中学数学教师的基本功,他们不仅要掌握二次方程的理论,而且还要运用技巧把一些高次方程转化为二次方程。现根据自己多年学习与教学的实践,给出一元四次方程的一种解法。予备知识:给定二元二次方程Ax~2+2Bxy+Cy~2+2Dx+2Ey+F=0(1)
Algebraic equations are one of the central topics of elementary mathematics. Good solution equation training is the basic skill of middle school mathematics teachers. They not only need to master the theory of quadratic equations, but also use techniques to convert some high-order equations into quadratic equations. Based on his own practice of years of study and teaching, a solution to the univariate quartic equation is given. Prep knowledge: Given binary quadratic equation Ax~2+2Bxy+Cy~2+2Dx+2Ey+F=0(1)
