So what's in the parentheses right here, this is the exact same thing as negative 1 squared times Y plus the expected value of negative Y. So that's the exact same thing in the parentheses squared. Everything in magenta is everything in magenta here, and it is the expected value of that thing. Now, what is the expected value of negative Y? The expected value of negative Y, I'll do it over here, the expected value of the negative of a random variable is just the negative of the expected value of that random variable. So if you look at this, we can rewrite this. I'll give myself a little bit more space.
