## Homework Statement

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

## Homework Equations

## 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 can't be negative, and if they are unequal then the discriminant can't be a perfect square

is this the right way to do this problem?
