MarkFL replied to a thread Find Value of k in Pre-Calculus
No, the roots themselves. Recall, if: ax^2+bx+c=0 then: x=\frac{-b\pm\sqrt{b^2-4ac}}{2a} What are the roots of the given quadratic?

MarkFL replied to a thread Find the Value of n in Pre-Calculus
Yes, the discriminant is what's under the radical in the quadratic formula, and it cannot be negative if the roots ore real. :D

But sixty days later, he found that he needs and so so sells the note to a third party for 3,550 Euros.
