Ximena Greene · Answer 1

= x (x + 8) - y (x + 8)

= (x - y) (x + 8)

Desirae Lawrence · Answer 2

Don't you see that y is a stranger. So group it - y (x+8)

The balance just happens to be x (x+8)

So you have these two terms. Take the common factor out.

(x+8) (x-y) now that's the answer. Easy ...
