Question

What is the difference between
(x + y)^2 and x^2 + y^2

Answer 1

2xy

Answer 2

Its like This
x=2 and y=3
(x+y)^2 = (2+3)^2
=5^2=25
x^2+y^2=2^2+3^2=4+9=13
hope u get it

Answer 3

(x+y)^2 = x^2 + 2xy + y^2

(x+y)^2 - (x^2+y^2) = (x^2 + 2xy + y^2) - (x^2 + y^2)
= x^2 + 2xy + y^2 - x^2 - y^2
= 2xy
