Pretty easy but i didn't listen to the course.

Your question: Please help. Pretty easy but I didn't listen to the course.

For next time: Sometimes people on can't get to every answer quick enough, which means you're left confused!  In order to figure out this question, all you have to do is enter in each equation; if they don't equal eachother, it's not the answer!

Such as: Enter a^2+3b-2a^2 (First part of the expression) Then, enter in the second part: 3a^2+3b-4a^2 (Which is after the equal/= sign.)

Good luck, mate!
