[x]+2[sqrt(x)]=2x-2

Read this first: Expectations for the Homework Help board
Do not simply retype or paste a question from your book or study material

We won't do your homework questions for you.
You were given the assignment for you to learn.

If you come up with your own answer and post it for us to critique that is within reason.

If you have some SPECIFIC questions that you couldn't find or didn't understand, we may help with that.
But this is your assignment, so show us you have at least attempted to complete it on your own.

Thank you.

Um... okay... but I don't see a question... :confused:

Only some equations and then..

Some explanation from the OP would be nice. But, I assuming those brackets indicate the floor function.

If so, then the first one would be x=0,1,4

I wonder why so many think that those on forums can read minds?

Want to bet they were in a class taking a test and was hoping for a quick answer so they wouldn't actually have to do it themselves.

Or if it was homework... a quick answer so it doesn't eat into their Playstation time.
