When the concentrations of H and OH are 1.5 M, isn't the pH and pOH negative?

It is normal for a pH or pOH value to be negative. If the concentrations are greater than 1.0, which in this case they are, then the pH/pOH values will be negative. This checks out mathematically.

Yes, whenever the H+/OH- concentration is greater than 1, pH/pOH will be negative
