Question

what is x square - y square over x + y

Answer 1

well, x^2-y^2 = (x+y)(x-y)

so ...

Answer 2

I mean x raise to power 2- y raise power 2 divided by x+y

Answer 3

so, now you have

(x+y)(x-y) / (x+y)

NOW do you see?

To simplify the expression (x^2 - y^2) / (x + y), we can use the difference of squares identity, which states that a^2 - b^2 can be factored into (a + b)(a - b). Let's apply this identity:

We have (x^2 - y^2) / (x + y).

We rewrite x^2 - y^2 as (x + y)(x - y):

= (x + y)(x - y) / (x + y).

Now, we can cancel out the common factor of (x + y):

= (x - y) / 1.

Therefore, the simplified expression is x - y.
