總之你點搵 a/b= ="":o :o
a =2 / 5
b =5 / 2

都唔知做乜:icon101::icon101::icon101:

你係a over b

定係

a或者b

好易mix up:icon101:
如果係a over b
咪係1 over 7囉:icon101:

應該話係alpha 定係a:icon101:

係alpha呀:o 唔q想打出黎:o :o你地以為x^2既coff over constant!?:icon101:

就咁x^2 - 7x +10邊有得factorize

係咪set條式 = 0先:o

咦....我以為你trick我地呢樣野...:icon101::icon101:

即係仲有其他trick:icon064:

點解1/7?:o
-b over a=sum of roots

好似係-1 over 7唔係1 over 7:icon101:

我知呀:o :o

而家搵 alpha over beta:o

你可唔可以scan
講左一大輪成班人都唔知問咩:icon101:一係由佢,唔好計啦:icon101:

你講呢個a,b坐corefficient before x and its power

佢講既a,b係roots of equation:)

(x - 2)(x - 5)
就咁睇我會咁拆

如果唔去考慮有冇trick野:icon101::icon101:

係喎..問下你丫...係maths勁...

如果 a,b 係 roots of x^2-7x+10

咁a/b = 乜??:o

係咪應該有=0

TAMTOM 發表於 2005-5-8 00:13:58

x^2-7x+10 ..根本無ROOTS.....

基維蝦 發表於 2005-5-8 00:14:13

算啦..我都唔知想點..:icon101:
