Betulkan mana yang salah

SambalBelimbing

Ada part yang salah kat persamaan bawah ni.. Betulkan..

X = 2

X(X-1) = 2(X-1)

X2-X = 2X-2

X2-2X = X-2

X(X-2) = X-2

X = 1

XXX :

loQlaQ

X(X-2) = X-2, kalo direngkaihkan jadi X(0) = X-2,
maka jika (0) dipindahkan ke seblah kanan, jadi /0

so, mushkilnya ada ka istilah /0 tu dlm maths equation?

@Elle_mujigae help! cum'ere n fix it

X(X-2) = X-2, kalo direngkaihkan jadi X(0) = X-2,
maka jika (0) dipindahkan ke seblah kiri, jadi /0 ...

eh tak perasan soalan ni...

haha..funny funny....let's try to fix it together,shall we...

This is a quadratic equation..erm..

X(X-2) = X-2, kalo direngkaihkan jadi X(0) = X-2,

loQlaQ, x=2 so 2(2-2)=2-2

so betul la kan... macam mana boleh jadi x=1 pula ye...

This part.....erm....
x(x-2)=x-2
x= x-2/(x-2)
x=1

owh..okay got it...

This part is wrong kan..

x(x-2)=x-2
x=(x-2)/(x-2)
x=1

but I don't know the reason...hehe

when we factorize the quadratic equation,we will get x=1,x=2......


x(x-2)=x-2
x^2-2x-x+2=0
x^2-3x+2=0
(x-1)(x-2)=0
(x-1)=0 , (x-2)=0
x=1, x=2

That one consider fix ke..huhu
tak puas hati sebab I don't know the reason why cannot bring (x-2) to the right..
I mean we know it is an algebra mistake,just dont know why..erm..=/

kalo dipindahkan (X-2) a k a darabX-2 tuh ke sebelah kanan, dia bertukaq jadi bahagiX-2 > bahagi2-2 > bahagi0 khen?

so, buleh ka istilah bahagi0 a k a /0 ituh???

Okay thank you for the link...I dah baca....

So mana datangnya y ?
since from the solution given,we need to state x is not equal to y .....

ops sori ceq ngaku wat silap pasai tanya hukum asas "cannot divided by zero" itu dari angle/konteks yg salah.
sepatutnya dia dah masuk hala quadratic khen? so, baik bakulsampahkan saja

eh,tapi bukan ke jawapan kat website tu kata sama yang mcm loQlaQ kata? kalau divide by 0=undefined?

tt tadi masuk tapi tak sempat explain pula...
