Question

What is true about the solutions of a quadratic equation when the radicand of the quadratic formula is a perfect square? (1 point) no real solutions two identical rational solutions two different rational solutions two irrational solutions?

Answer 1

When the radicand is a perfect square and we pull it out, the determinant is then equal to 0. When this happens, we have two identical rational solutions. It is also called muliplicity 2.
