我们知道,一元n次方程当n≥3时,称为高次方程,五次和五次以上的方程可以证明它没有一般解的公式,三次和四次方程虽有求解公式,但不属中学教材范刚,因此在中学特别是初中解高次方程,也只能是一些高次方程的特殊类型。初中代数三册(1981年版)简单的高次方程一节,除介绍双二次方程外,尚有
We know that when n ≥ 3 in a single n-th order equation, it is called high-order equation. Equations with five or more times can prove that it has no formula for general solution. Although there are solution formulas for the third and fourth-order equations, they are not secondary schools. The textbook Fan Gang, therefore, can only be a special type of high-order equations in secondary schools, especially the junior high school equations. Junior high school algebra three volumes (1981 edition) simple high-order equations section, in addition to introducing bi-quadratic equations, there are
