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?
