Question

1 is = 2 how please explain​

Answer 1

Let a = b

then a^2 = ab

a^2 - b^2 = ab - b^2

(a+b)(a - b) = b(a - b)

a + b = b

but a= b

thus

b + b = b

2b = b

2 = 1

Hence proved

Answer 2

Hey There.....!!

Let a = b

a^2 = ab

a^2 - b^2 = ab - b^2

(a+b) (a-b) = (a-b)b

a + b = b

but,

a = b

b + b = b

2b = b

Hence,

2 = 1

Hope this helpß!!
