Need help on algebra 2 homework
DrMobius:
He's factoring. What the hell do you think? His order of operations is fine. I'm not terribly sure why he would give (x - y) as an exponent.

I had a revelation.

or x equals three and negative three plus or minus three i times the square root of three over two

How can you still not know the order of operations?
