Math, microeconomics or criminal justice
b^2 -4ac = 16-4(5)(11 <0
when the discriminant <0 there are no real roots, just 2 imaginary roots
when b^2-4ac = 0, there's one root with multiplicity 2
when b^2-4ac>0 there are 2 real roots
a, b and c come from ax^2 + bx + c
a is the coefficient of the squared term
b is the coefficient of the x term
c is the constant term
