A)    Assuming that a = b

à a x a = a x b

à a x a – b x b = a x b – b x b

à a² – b² = b x (a - b)

à (a + b)(a – b) = b x (a – b)

à a + b = b

à b + b = b

à 1 + 1 = 1 or 2 = 1

 
B) 2 Become 1 --- by Spice Girls

Candle light and soul forever
A dream of you and me together,
Say you believe it, say you believe it,
Free your mind of doubt and danger,
be for real don't be a stranger,
We can achieve it, we can achieve it
Come a little bit closer baby, get it on, get it on,
Cause tonight is the night when two become one

I need some love like I never needed love before
(wanna make love to ya baby)
I had a little love, now I'm back for more
(wanna make love to ya baby)
Set your spirit free, it's the only way to be
