Question

Expand and simplify
(x- y)²

Answer 1

x²-2xy+y²

Explanation:

(x-y)² is the same as (x-y)(x-y).

First you would do x×x=x²

Then you would do x×-y= -xy

After that you do -y×x= -xy

Then do -y×-y= y²

You would then put it into an equation like this:

x²-xy-xy+y²

And then simplify it to:

x²-2xy+y²

Hope this helps :)
