So I'm going to go into that same color I had. So we're going to have 4 minus x squared plus 2x times 4 minus. Actually, let me write that in the order of the terms or the degree of the terms. It's negative x squared plus 2x plus 4. I just switched the order of these things. Times negative x squared plus 2x plus 4. So we're just going to multiply these two things.
