Batches That Maximize Profit

A bakery's daily profit, in hundreds of rupees, from baking $x$ batches of bread is

$P(x) = -2x^2 + 12x - 5$

Because every maximization is the same problem as a minimization of the flipped function, the bakery works with

$\min_{x} \; \left(-P(x)\right) = \min_{x} \; \left(2x^2 - 12x + 5\right)$

What is the setting of $x$ that solves this problem?
