I'm not sure how it is if you're making the question, but in the reply here I clicked on equation, then put it in using the options.

The like terms apply to what follows the number, so in this case "x" "y" and nothing (your basic numbers). I suggest starting by moving the like ones together so they are next to each other rather than spread out. Remember that the sign in front (addition or subtraction) must go with it. So your new equation would be: 7x+ 6x + 3y - [y ^{2}\] -2 -1 Then combine them. You can combine the two x terms together using addition, and the -2 and -1 together. Because the second y is squared you can't combine it with the other y though. Also, I believe it's generally customary to but all squares out in front, so put that, then your xs, then y, then numbers.
