一元n次方程問題

係度我比晒中英文的寫法你, 因為我唔知閣下讀的係中文定英文課程.

中文:
n 個答案重複可以表達成 "n 重根"
根據餘式和因式定理, 若多項式 f(x) 可被寫成 f(x) = g(x) (x-k)^n, 則方程式 f(x) = 0 就有一個 n 重根, 其數值為 k.

English
n-time repeated roots can be expressed as "roots with multiplicity n"
According to the remainder and factor theorems, if function f(x) can be expressed as f(x) = g(x) (x-k)^n, then equation f(x) = 0 has a root k with multiplicity n.

你重複一元一次方程三次就得 la!>=
