Question

let a=b
multiplying both side by a
a²=ab
subtracting b² from both side
a²-b²=ab-b²
(a+b)(a-b)=b(a-b)
dividing both side by (a-b)
a+b=b
now as we know a=b
so a+b = b+b
2b
so
2b = b
dividing both side by b
2=1
how?
what is wrong​

Answer 1

Step-by-step explanation:

what is wrong

the thing that is wrong is that

you have said a=b

for eg take a=2

and fr above

a^2-b^2

2^2-2^2

0

and when...you subtract b^2 from a^2 the answer will be zero....and when....you use zero in maths...weird things happen and your above explanation/thingy is wrong

if it helps you mark it as the brainliest
