Find the set of values of for which the equation, has 2 distinct roots.

While I know that this question can be solved by using using the equation , I do not understand why can be ignored. Why is it that only the top of the fraction is considered?

You may ignore the bottom only at your peril!!

Before I thought I had a solution, I would want to know that x=a does NOT make the numerator vanish. - Dec 7th 2011, 04:03 AMHallsofIvyRe: discriminant (fraction)
However, your basic problem with finding "the set values of a for which the equation has 2 distinct roots" is that you don't has an

**equation**!
