Step-by-step explanation:For the first one in parentheses you can't do it because their has to be an x with the two so you can do the problem.
For the next one you can do it. So for every letter that doesn't have a number their is always an invisible 1 in front of it. So it's 1x to the second power + 1x-1 so 1×1 is 1. 1x+1x=2x and the 2 and the one that doesn't have a letter equals 3. So the answer is
2x × 3 Hopefully this is correct and helps you out!
