Find error

[Zeeshan Haider]

یہ حسابی مساوات کا ثبوت ہے۔ کیا آپ بتا سکتے ہیں کہ اس میں کیا غلطی ہے؟

a = b
aa = ab (Multiplying 'a' both side)
aa - bb = ab - bb (Subtrating 'bb' from both side)
(a + b)(a - b) = ab - bb (using formula)
(a + b)(a - b) = b(a - b)
a + b = b (Dividing (a - b) both side)
a + a = a (substituting a with b because a = b)
2a = a
2 = 1 (dividing a both side)

a = b
aa = ab (Multiplying 'a' both side)
aa - bb = ab - bb (Subtrating 'bb' from both side)
(a + b)(a - b) = ab - bb (using formula)
(a + b)(a - b) = b(a - b)
a + b = b (Dividing (a - b) both side)
a + a = a (substituting a with b because a = b)
2a = a
2 = 1 (dividing a both side)

agar a = b hai
to phir a - b = 0 hoga or zero se division nahi hoti
main ne error bold kardia hai i think i could be the right answer

do different constant kabi bhi equal nahi ho sakte......
Hamari Supposition hi wrong hai...
a=b
agar asa ho to 2=1 kia 1=10000 bhi ho sakta hai...
?????

YES HAZA TAQ is RIGHT :P

آپ ٹھیک کہہ رہے ہیں۔ دو کونسٹنٹ کبھی برابر نہیں ہو سکتے۔ لیکن یہ ثبوت تو کچھ اور ہی کہہ رہا ہے۔ آپ کو اس ثبوت میں غلطی نکالنی ہے۔

Second step main aa=bb hai to ager aap ne us main se bb ko Substract kiya to anser yeh hona chahiye:

bb-(aa)=bb-(ab)
bb-aa=bb-ab
if a=b
then
aa-aa=aa-aa
0

[Hazataq]

nahi yr ye setup thek hai bb me se subtract nahi kia bb ko subtract kia hai
error kahi aur hai...

[haroonsameed]

koi galti ni h ye math ka fault hai

[shaaaz]

is main ghalti ye hai k....
2 = 1
Q k...
1 kabhi 2 k barabar nahi ho sakta....

[usman]

agar a = b hai
to phir a - b = 0 hoga or zero se division nahi hoti
main ne error bold kardia hai i think i could be the right answer

ye theek hai aur koi ghalti nahi lagti

acha yar wohi bta dey

False Suppostion Leads you to False Result...
You Suppose two Variables having same constant value i.e
a = b will only be equal if both have same constant value, but in the end both have different constant value......

Look at Different Angle

you suppose a = b which means a-b =0
while your result is 1=2 , can you obtain 1-2 = 0 from your result...
if you can't then your suppose a=b is wrong
