Question

How would I find the discriminant of 3x^2+2x-7 and what does it ell me about the equation?

Answer 1

\[\sqrt{b^2-4ac}\]

Tells you whether there are real solutions or not.

Answer 2

If the value under the square root is positive, then real solutions exist.
If the value under the square root is negative, then no real solutions exist.

Answer 3

Oh, and Hi
