Question

Explain why a positive discriminant results in two real solutions.

Answer 1

Answer:

Step-by-step explanation:

If the discriminant b^2 - 4ac > 0, then the two solutions are

$\frac{-b +- \sqrt{b^2 - 4ac} }{2a}$, and in both cases, the value on the square root is > 0, so the result will always be a real number.
