I'm sorry...when I am asked a question in standard English, I'm more than happy to try to help.

When I'm asked a question in "chat-speak," my response is "Ask one of your texting friends."

How would you do x^2+2x-15 ?

 

[estephani35]

x^2+2x-15

(X )(X )
(X 3) (X 5)
(X - 3) (X + 5)

 

[Denis]

x^2+2x-15
(X )(X )
(X 3) (X 5)
(X - 3) (X + 5)

So now insert the y's: (x - 3y)(x + 5y) ; kapish?

ooooooooooooooooohhh
ok

so x^2 + 2xy -15y^2=
(x - 3y) (x+ 5y)
