Originally posted by Raul at 2005-5-7 22:53: 你係a over b 定係 a或者b 好易mix up
Originally posted by Raul at 2005-5-7 10:54 PM: 如果係a over b 咪係1 over 7囉
Originally posted by MatthewChor at 2005-5-7 10:57 PM: 應該話係alpha 定係a
Originally posted by 阿忠 at 2005-5-7 11:04 PM: 就咁x^2 - 7x +10邊有得factorize 係咪set條式 = 0先
Originally posted by 基維蝦 at 2005-5-7 11:04 PM: sorry
Originally posted by 基維蝦 at 2005-5-7 22:57: a over b 點解1/7?
Originally posted by 阿忠 at 2005-5-7 11:06 PM: 咦....我以為你trick我地呢樣野... 即係仲有其他trick
Originally posted by Raul at 2005-5-7 11:08 PM: -b over a=sum of roots
Originally posted by 基維蝦 at 2005-5-7 23:09: 我知呀 而家搵 alpha over beta
Originally posted by Raul at 2005-5-7 11:08 PM: -b over a=sum of roots 好似係-1 over 7唔係1 over 7 [ Last edited by Raul on 7-5-2005 at 11:09 PM ]
Originally posted by 阿忠 at 2005-5-7 23:10: 你講呢個a,b坐corefficient before x and its power 佢講既a,b係roots of equation
Originally posted by 基維蝦 at 2005-5-7 11:08 PM: 我真係唔識
Originally posted by 阿忠 at 2005-5-7 11:11 PM: (x - 2)(x - 5) 就咁睇我會咁拆 如果唔去考慮有冇trick野
Originally posted by MatthewChor at 2005-5-7 11:13 PM: same as me
Originally posted by 基維蝦 at 2005-5-7 10:47 PM: 係喎..問下你丫...係maths勁... 如果 a,b 係 roots of x^2-7x+10 咁a/b = 乜??
