(x²+y²)=(x-y) × (x + y) { it is a formula }
x=2
y=1
(2-1) × (2+1)= 1 × 3 = 3

ya sorry
i didn't saw the minus and plus
the correct formula of (x^2 + y^2) = (x+y)^2 - 2xy or (x^2 + y^2) = (x+y)^2 +2xy
its just a simple sum
no need to be so complicated
just square both the no.s and add then
it's them
yoo ...know
ok bye guys
bye
