if your quadratic has rational roots then it would factor, it does not
Also the discriminant would have to be a perfect square for rational roots. It is not.

b^2 - 4ac = 25-4(1)(3) = 13

so you would have two different irrational roots
Answered by bobpursley
b^2-4ac= 25-12=13

and exactly what is sqrt 13? I took it to 13 digits, and didn't see numbers repeating. Why did you say rational?
