So plus 3x, and we're going to evaluate it from 0 to 5 halves. So this is going to be equal to 5 plus, and I'll do all of this stuff right over here. I'll do this stuff in green. So when we evaluate it at 5 halves, this is going to be negative 5 halves squared. So it's going to be negative 25 over 4 plus 3 times 5 halves, which is 15 over 2. And then from that, we're going to subtract this evaluated at 0. But negative 0 squared plus 3 times 0 is just 0.
