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. So this is what it simplifies to. And so what do we have right over here? So let's get ourselves a common denominator.
