How to Factorize a Cubic Polynomial โ Mashup Math
A cubic polynomial is of the form p(x) = a 3x3 + a 2x2 + a 1x+ a 0: The Fundamental Theorem of Algebra guarantees that if a 0;a 1;a 2;a 3 are all real numbers, then we can factor my polynomial into the form p(x) = a 3(x b 1)(x2 + b 2c+ b 3): In other words, I can always factor my cubic polynomial into the product of a rst degree polynomial

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.

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:

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

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.

1 Group the polynomial into two sections. Grouping the polynomial into two sections will let you attack each section individually. [1] Say we're working with the polynomial x 3 + 3x 2 - 6x - 18 = 0. Let's group it into (x 3 + 3x 2) and (- 6x - 18) 2 Find what's the common in each section. Looking at (x 3 + 3x 2 ), we can see that x 2 is common.

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.
