a complex calculation

hi guyz how r u 2day
I found something is very important
it is about the math
i found something will change our informations
we will take a look a Q and we will ask our self is it true
if it is not so tel us where is the problem
our our informations are not correct
that is mean we lost our years to study not
ok let us take a look for it


let a=b
multiply each side by a
a.a=a.b
add each side a.a
a.a + a.a = a.a + a.b
add -2.a.b
-2.a.b + a.a + a.a = a.a + a.b - 2.a.b
it will be come
a.a + a.a - 2.a.b = a.a - a.b
this can written as
2(a.a - a.b) = 1(a.a - a.b) is it correct
now we will divide be
(a.a - a.b) and look the result
it will be 2=1
so is it true or what



thanks
