(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Barry has just solved a quadratic equation. He sees that the roots are rational, real, and unequal. This means the discriminant is

a) zero, b) negative, c) a perfect square, d) a non perfect square

2. Relevant equations

3. The attempt at a solution

I think the answer is d) a non perfect square

if the roots are real and rational then the discriminant cant be negative, and if they are unequal then the discriminant cant be a perfect square

is this the right way to do this problem?
