    And hOW the fuck am I supposed to factor cubic equations? Guess?

If all the coefficients are integers, as it is the case here, rational root theorem and Horner's method might be enough to do it fast. Though, Cardano's method is a much more general way of solving cubics and worth learning at some point.
