Xazzath, Algebraic Ruler

Xazzath's power and toughness are equal to
the sum of the results of the quadratic equation "ax^2 + bc + c =. 0"" where a is your life total, b is the greatest power among creatures you control, and c is the number
of cards in your hand multiplied by -1. (If
the result includes i, just deal with it.)
Whole numbers? Ha!
