If we have a = b then
a^2 = ab
a^2 – b^2 = ab – b^2
(a + b) (a – b) = b (a – b)
a + b = b
2b = b as a=b
2 = 1

Which Law of Maths is violated if any ?

at (a+b)(a-b)=b(a-b), when you got result a+b=b you divided by zero. if a=b, then a-b=0.

My Alg II teacher taught me the same basic thing in 11th grade:

x=1
x*x=x*1
x^2=x
x^2-1=x-1
(x+1)(x-1)=(x-1)
x+1=1
1+1=1
2=1

same thing, different variables
