Answer 4

I got 5x^2-4 i just wanted to make sure it was right because it counts for like 15 points :P

Answer 5

That's a lot of points, but they probably made it worth that much because it is something you should definitely know how to do.

Answer 6

Always place like terms together, and if you're still stuck or doubtful about your steps, you can factor out the variables and write it like this:

\((2 + 3)x^2 + (11 - 11)x - 4\)

Answer 7

Now it is even more obvious
