I'm kind of embarrassed to ask this question since I am in calculus but how would I factor the following? I know you can multiply 3*-6 and you get -18 and somehow you then can factor. But I can't seem to do it.

3x^2 + 2x -6
Any help please?
since the discriminant is not a perfect square number, the quadratic will not factor.

Hmm... I see. Well, I'm trying to find the local extrema and that equation happens to be the second derivative. I don't know how to get the max and min point out of that now.

you don't need to know where f''(x) = 0 to find extrema ... inflection points, yes, but not extrema.
