How to Factor a Cubic Polynomial 12 Steps (with Pictures)
Factoring cubic polynomials is a process of expressing the cubic polynomials as a product of their factors. We can find the factors of a cubic polynomial using long division methods, algebraic identities, grouping, etc. A cubic polynomial has a standard form ax 3 + bx 2 + cx + d, where a, b, c, d are real numbers.

A cubic polynomial is a polynomial of the form f (x)=ax^3+bx^2+cx+d, f (x) = ax3 +bx2 +cx+ d, where a\ne 0. a = 0. If the coefficients are real numbers, the polynomial must factor as the product of a linear polynomial and a quadratic polynomial.

What does it mean to factorize a cubic polynomial? In math, the factors of any polynomial represent components or "building blocks" of the polynomial. Whenever you factor a polynomial (cubic or otherwise), you are finding simpler polynomials whose product equals the original polynomial.

To factorise a cubic, you need the value of b (and sometimes a ). To find this factor, use the factor theorem. The factor theorem says that, for a function f ( x ): if is a factor, the ; if is a factor then . For example, the cubic below has a factor of : You can show this by calculating f (-2); if ( x + 2) really is a factor, f (-2) will equal 0:

The most reliable method of finding other the other factors of a cubic is with polynomial long division. Polynomial long division works similarly to regular long division with numbers. We'll finish factoring \(f(x)=x^3 +8x^2+21x+18\) as an example, and we'll describe each step in detail.
How to Factor a Cubic Polynomial 12 Steps (with Pictures)
A cubic polynomial is an expression with the highest power equal to \(\text{3}\); we say that the degree of the polynomial is \(\text{3}\). The general form of a cubic polynomial is. In Grade 10 we learnt how to factorise the sum and difference of two cubes by first finding a factor (the first bracket) and then using inspection (the second.

Zero is the easiest to check because that would mean the constant term is zero, thats not the case here. 1 doesn't work because that would be 1 โ 6 + 4 = โ1 โ 0. 2 happens to work since this would be 23 โ 6 โ 2 + 4 = 8 โ 12 + 4 = 0. Since 2 works, we know that the equation can be factored as (x โ 2)q(x) where q(x) = x3โ6x+4 xโ2.

Factorization aims to represent a polynomial as a product of two (or more) lower degree polynomials. The factorization is complete when the resulting factors are irreducible. The Standard Form of Cubic Polynomial As we are focused on the cubic polynomial, we need its standard form for our discussion. Standard form of the Cubic Polynomial

FactorisationThe ac Method Cubic EquationsQuartic Equations Cubic Equations If f(x) is a cubic function ax3 + bx2 + cx + d then the equation f(x) = 0 can have up to three real roots. Note: The number of real roots will depend upon the values of a, b, c and d. Factors of the cubic clearly give us its roots. e.g.s: x3 6x2 + 11x 6 = 0
