1: How can you determine if ax2 + bx + c is prime?
The quadratic formula guarteen that the quadratic
form is never prime in the Complex Number System.
It IS prime in the Real Number System if b^2-4ac is
a negative number.

Use the Quadratic formula to find roots r1 and r2.
The factors are then (x-r1) and (x-r2)
