The remainder theorem is too simple that school teacher never teaches ? My school teacher also never taught but I had seen a few examples and self-learning and find that it is too easy! I recalled when I was sitting for Secondary-5 National exam .I borrowed S-3 and S-4 New MODERN maths and Self-learning .It was too easy , I glance through 2 years school textbook within one day :It was extremely easy that just the Symbols Notations Changes you never see before! The rest are familiar maths. When come to S-5 exam , the test addin 30% new Modern Maths which my schook teacher never teaches us .You can guess the examiner do not want students to get grade-A in MATHS . I attended the New Modern Maths and got grade-A++ .The whole country only 3 persons who get grade-A .Majority get grade-C and below and a few get grade-B .
教的很好啊!怎么有人不喜欢啊?
感謝老師指教
唔該晒您~!
好有心機thx
hkcee 2007 p2 q40.
ans 點解係x,而唔係2x既?
2, x 和 2x 都可把 f(2x+1) 整除。但該題是選擇題,只有 x 這選項。
都係唔明點解 x 係答案 點樣被整除? 2x 不是已經為因式嗎
+LI Wallace 如果一個數可被6整除,這數字亦必定可被3整除,原因是6可寫成 2×3。而所謂 2x 其實就是 2×x。既然可被 2x 整除,該數式亦必定可被 x 整除。
Thx
THX!!
如果調轉,問2x+1是何者因式,點做?
用返餘式定理 Remainder Theorem,即是把 -1/2 代入各多項式,結果是零就是。
👍👍
真心多謝你禁有心教!!
Thank you! 加油!!
教的很好^_^
教得好,除咗可否唔將x講做s
