Question

How to reduce x*x-y*y/x-y to x+y?

Answer 1

x*x-y*y/x-y

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

x+y

Answer 2

Your Numerator: x square - y square

Your Denominator: x - y

Now you must know the formula:

x square - y square = (x+y)*(x-y)

So, canceling the (x-y) from the numerator by the denominator, u get:

(x+y)            

So there you are! Just a formula to mug-up.

Best of Luck
