Cubic Formula: Step-by-Step Solution for Finding x

In summary, the cubic formula is a mathematical formula used to solve cubic equations, which are equations in the form of ax^3 + bx^2 + cx + d = 0. To solve a cubic equation using the cubic formula, one must identify the values of a, b, c, and d and plug them into the formula to find the three possible solutions for x. The general form of the cubic formula is x = (-b ± √(b^2 - 4ac - 27d^2)) / 2a. It is always possible to solve a cubic equation using the cubic formula, but there are other methods that may be more practical. The cubic formula has various applications in science, engineering, and
