### How to Factor a Cubic Polynomial: 12 Steps (with Pictures)

2020-01-23· This is an example of "the sum of cubes" (because x³ is the cube of x, and 27 is the cube of 3). The formula for factoring the sum of cubes is: a³ + b³ = (a + b) (a² - ab + b²). In this case, a is x, and b is 3, so use those values in the formula.

Factoring in Practice. If a given cubic polynomial has rational coefficients and a rational root, it can be found using the rational root theorem. Factor the polynomial. 3 x 3 + 4 x 2 + 6 x − 35. 3x^3 + 4x^2+6x-35 3x3 +4x2 +6x−35 over the real numbers. Any rational root of the polynomial has numerator dividing. 35.

### The "Cubic Formula"

This trick, which transforms the general cubic equation into a new cubic equation with missing x 2-term is due to Nicolò Fontana Tartaglia (1500-1557). We apply the substitution to the cubic equation, to obtain: Multiplying out and simplifying, we obtain the "depressed" cubic Let's try this for the example 2x 3-30x 2 +162x-350=0. Our substitution will be x=y+5; expanding and simplifying, we ...
