you’ve saved my life :))) post more :)))
Thank you very much You have saved my daughter’s life.😁😁😁
每次大考前都來溫習一次\(^o^)/~

so good it helps a lot, thank you so much!!!
this gives me nostalgia in being taught math in chinese, now its fully english
Mid term test 有很大幫助😄
第二題例子點醒我 thx
🎉🎉🎉🎉
Thanks
No 11 why didn't you include the 8 in the 2ab part? Thank you
don't understand your question fully. 1 , -2 , -8 are the three numbers when it's in descending powers of "3a+4". so we input 1, -2, -8 to get the answers.

如果唔係全部二次方,係一個二次方,一個三次方既話點計?
例如4x^3 - 6x^2y
sorry for disturb, 請問 81X^3-3y^3 有冇得計thx
呢個就沒有了,要靠自己努力了
為什麼4x+4不可?
這個 program 只做 quadratic form (x 二次方那種) 及其變化形式。4x + 4 抽 common factor "4" 便可。
Thank
想問吓點解第七題要先抽個負號?負號算係common factor?
可以當係既. 當抽 "負1"
我這邊還有一些題型沒有啊⋯⋯還是我搞錯了?xy-4y二次-(x-4y)二次,還是根本不是這種東西?
不好意思, 之前 miss 了你 comment這個不是這類. 是抽 common factor 和 grouping term. xy - 4y² - (x - 4y)²= y(x - 4y) - (x - 4y)² (頭兩項抽 y 做 common factor)= (x - 4y)(y - (x - 4y)) (抽 (x - 4y) 為 common factor)= (x - 4y)(y - x + 4y)= (x - 4y)(5y - x)
👍🏻👍🏻👍🏻
I wonder which kind of people disliked this video...
點解要變倒數?😵💫
very good video
Omg thank you so much!
可唔可以將個答案抄返落個cross method度
一定可以的。老師要求寫 cross method 個 step?
咁長除式呢?可唔可用撳機?
webcal.freetzi.com/casio.fx-50FH/fx-50F_Plus.htm可以參考 B3, B4, B5
@@chericiu 咁我用fx50-H II呢個型號計算機
good video thank you
Y i have math error
if you see Math Error, then the expression cannot be factorized. (的確有一些東西是無法 factorize 的. e.g. x² + x + 1)
多謝
Thx!
有冇字幕?
不好意思, 不太懂做
omg thxxxx
妙!
咁帶分數呢
先轉返做假分數. 可按 "shift a b/c"如果想永久自動顯示假分數, 就按 shift mode --> --> 2 (d/c)
👌 明了,謝謝
@@DaveLau0313 出 extra 講假分數應該未必會了,我儘量在這裏答你,睇下你明唔明吧。Example: Factorize 12x² - 13x - 55. 按 formula-01 會出到 2.75 按"a b/c" 變成 11/4 Factor 是 (4x - 11)-1.666... 按"a b/c" 變成 -5/3 Factor 是 (3x + 5)so the answer is 12x² - 13x - 55 = (4x - 11)(3x + 5)
学校要求写step
那你怎么办
so?
