**How to solve cubic equation step by step by suzann Issuu**

The problem is that you can't always find a factor easily, where as the formula always works. I mean, how would you solve I mean, how would you solve x^2 + 23x + 7 = 0 by using just the factor theorem and not the formula/completing the square/some other method which isn't the factor theorem?... This is easily done by dividing the equation by the leading coefficient, leaving us with the general cubic equation: (1). The first step to solving the cubic is to eliminate the term, which makes the calculations simpler, as the Italian mathematicians of the 16th century found out. This is done by letting . From this, we can deduce that: (2), so (3), for some constants A and B. We shall write
