generate a equation using at least five numbers; 0 (zero), two even, and two odd to get a prime number. For example; (a) x = 0 => x2 – x + 41 = 0 – 0 + 41 = 41, which is prime. (b) Two even:

x = 2 => x2 – x + 41 = 22 – 2 + 41 = 4 – 2 + 41 = 43, which is prime. x = 4 =>

x2 – x + 41 = 42 – 4 + 41 = 16 – 4 + 41 = 53, which is prime. (c) Two odd: x = 1 =>

x2 – x + 41 = 12 – 1 + 41 = 1 – 1 + 41 = 41, which is prime. x = 3 => x2 – x + 41 =

9 – 3 + 41 = 6 + 41 = 47, which is prime.
