1. ## Is it possible to factor (3x^2 - 4)?

I'm curious if this is possible? And if yes, how so?

The context of my problem is finding local minima and maxima and whether f(x) is increasing/decreasing.

$(\sqrt{3} x - 2)(\sqrt{3} x + 2)$

3. Cool thank-you.

wouldn't that be 3x only

Expand out what you think it should be and then expand out what skeeter said it is ....
