Why is the formula for the determinant (b^2-4ac)^(1/2) instead of ad-bc?

I think the OP was confused. They were referring to the discriminant, something you use in the quadratic formula. The formula for the determinant is different for every matrix, but for a 3x3 one is very hard to type out. It might be easier to Google it.
