For any quadratic polynomial equation of the form:
Find the Discriminant, 
and evaluate the nature of the roots as follows:
No calculation quick look: If the signs on 
and 
are opposite, then 
guaranteed.
Two real and unequal roots. If 
is a perfect square, the quadratic factors over 
(the rationals).
One real root with a multiplicity of two. That is to say that the trinomial is a perfect square and has two identical factors. Presuming rational coefficients, the root will be rational as well.
A conjugate pair of complex roots of the form 
where 
is the imaginary number defined by
