Which does not determine a 3 3 6 3 4 5 3 5 7 or 3 6 6

3 3 6, because in every triangle the longer side is always shorter than the sum of the other two

answer:

The discriminant is the (b^2-4ac) part of the quadratic formula...in this case:

64-48=16

So there will be two real rational solutions.

The rule:

If discriminant<0, there are no real solutions (although there are two imaginary solutions)

If discriminant=0, there is only one real solution.

If discriminant>0, there are two real solutions.
