Simplify (x-y)²?

(x-y)^2
=(x-y)(x-y)
=x(x-y)-y(x-y)
=x^2-xy-yx+y^2
=x^2-2xy+y^2.
Actually, (x-y)^2 is in simplified form. What i did was to expand it. Hehe.. Hope u lyk my answer.

( x - y ) ( x - y )
x ² - x y - x y + y ²
x ² - 2 x y + y ²

= (x + y)²
= x² + xy + xy + y²
= x²+ 2xy + y²

(x-y)²

=(x-y)(x-y)

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

=x^2-2xy+y^2 #

Simplify X Y 2

x2+y2-2xy

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

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

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

(x-y)² <use the method of (a-b)²>

(a-b)² = a² - 2ab + b²

thus, (x-y)² = x² - 2xy + y²
