Factor Solve These Cubic Equations In Less Than A Minute Otosection
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.
How to factor a cubic function YouTube
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:

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.

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 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

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.

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

A general cubic equation is of the form (1) (the coefficient of may be taken as 1 without loss of generality by dividing the entire equation through by ). The Wolfram Language can solve cubic equations exactly using the built-in command Solve [ a3 x^3 + a2 x^2 + a1 x + a0 == 0, x ].

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 − 6 + 4 = −1 ≠ 0. 2 happens to work since this would be 23 − 6 ⋅ 2 + 4 = 8 − 12 + 4 = 0. Since 2 works, we know that the equation can be factored as (x − 2)q(x) where q(x) = x3−6x+4 x−2.
