本文目的在于用具体例子介绍某些解方程的“非标准”方法。要注意,文中的参数和未知数都只限于实数值。在变量代换中,常常采用被称为“算术平均”的代换。正如所见,用它能够消去未知数的奇次幂。
The purpose of this paper is to introduce some “non-standard” methods for solving equations with specific examples. It should be noted that both the parameters and the unknowns in the text are limited to real values. In variable substitution, substitutions called “arithmetic mean” are often used. As you can see, use it to eliminate the odd power of the unknown.
