lurflurf, did you check the answer choices?
Which answer choice would that be? And is there a more detailed way you can explain it, because I still don't get it.
Can you show it like step-by-step or something?
That's not one of the valid answer choices...
It's one of these four (it's multiple choice):
A) 2x
B) x²-2xy+y²
C) -2xy+y²
D) 2xy-y²
Thanks for your help, but I would like to get an answer that is Correct and WITH WORK.
I really don't know how to solve this.
I've got a question maybe you guys can answer.
I'm in Algebra II and I was given a question that was worded like this:
"If f(x) = x², then find f(x-y)-f(x)."
Can someone help me? I don't really know how to solve it...
