Question

The discriminant of a quadratic equation is 35. The roots are:

a) unequal rational numbers
b) unequal irrational numbers
c) equal rational numbers
d) imaginary numbers

Please explain.

Answer 1

I think it's B, unequal irrational numbers. But if the discriminant is 35 then this is not a perfect square.

Do they give you the whole equation such as x^2 + 6x + 5 = 0?

Answer 2

It is B.
