We could actually do it this way as well. But that's just going to be 4 times 4, which is 16. Plus 4 times negative x, which is negative 4x. Negative x times 4, another negative 4x. And then negative x times negative x is equal to plus x squared. So if we were to swap the order, we get x squared minus 8x plus 16. But we're going to subtract this.
