Hello, I have a question regarding this question. This is quite embarrassing to ask, but my online homework thing doesn't like the answers I'm giving.
I had to simplify a complex rational expression and my answer was: x/x+3 (which the homework thing said it was right). Now it's asking me to submit the numbers where x cannot be a certain number - that makes it undefined.
Now I inputted -3, but it said it was wrong so are there any other numbers that makes it undefined?
Thanks!
