| For Round 4, each contestant found the difference between the number of letters in his or her first name and the number drawn in Round 1. If the difference was even, the contestant had to write the perfect square trinomial formed by squaring the sum of x times this difference and y times the number drawn in Round 1. If the difference was odd, the contestant had to write the perfect square trinomial formed by squaring the result for x times the difference minus y times the number drawn in Round 1 | |
