And then p times p squared is p to the third. Now, we can simplify these. p to the third cancels out with p to the third. And then we have p squared minus 2p squared. So this right here becomes, you have this p right over here, so this is equal to p. And then when you add p squared to negative 2p squared, you're left with negative p squared. So minus p squared. And if you want to factor a p out of this, this is going to be equal to p times, if you take p divided by p, you get a 1, p squared divided by p is p. So p times 1 minus p. Which is a pretty neat, clean formula.
