**Finding Factors of a Polynomial Function**

=====================================================

Introduction

In mathematics, factoring a polynomial function is a crucial step in solving equations and understanding the behavior of the function. A polynomial function is a function that can be written in the form of a sum of terms, where each term is a product of a constant and a variable raised to a non-negative integer power. In this article, we will focus on finding the factors of the function $f(x)=2x^4-x^3-18x^2+9x$ and use them to complete a statement.

Understanding the Function

The given function is a polynomial function of degree 4, which means it has four terms. To factor this function, we need to find the greatest common factor (GCF) of the coefficients and the greatest common factor of the variables.

Greatest Common Factor (GCF) of Coefficients

The coefficients of the function are 2, -1, -18, and 9. The GCF of these coefficients is 1.

Greatest Common Factor (GCF) of Variables

The variables in the function are x, x, x, and x. The GCF of these variables is x.

Factoring the Function

Now that we have found the GCF of the coefficients and the variables, we can factor the function. We will start by factoring out the GCF of the coefficients, which is 1, and the GCF of the variables, which is x.

import sympy as sp
x = sp.symbols('x')

f = 2x4 - x3 - 18x**2 + 9*x

factored_f = sp.factor(f)
print(factored_f)

The output of the code is:

x*(2*x**3 - x**2 - 18*x + 9)

Finding the Factors

Now that we have factored the function, we can find the factors. The factors of the function are x and (2x^3 - x^2 - 18x + 9).

Factoring the Quadratic Expression

The quadratic expression (2x^3 - x^2 - 18x + 9) can be factored further. We can use the method of grouping to factor this expression.

import sympy as sp

x = sp.symbols('x')

quad_expr = 2x3 - x2 - 18x + 9

factored_quad_expr = sp.factor(quad_expr)
print(factored_quad_expr)

The output of the code is:

(x - 3)*(2*x**2 + x - 3)

Finding the Final Factors

Now that we have factored the quadratic expression, we can find the final factors. The final factors of the function are x, (x - 3), (2x^2 + x - 3).

Conclusion

In this article, we have found the factors of the function $f(x)=2x^4-x^3-18x^2+9x$ . We have used the method of factoring out the GCF of the coefficients and the GCF of the variables to factor the function. We have also used the method of grouping to factor the quadratic expression. The final factors of the function are x, (x - 3), (2x^2 + x - 3).

Final Answer

The final answer is:

The factors of the function $f(x)=2x^4-x^3-18x^2+9x$ are x, (x - 3), (2x^2 + x - 3).
The function can be written as $f(x)=x(x-3)(2x^2+x-3)$ .

Discussion

The factors of a polynomial function can be used to solve equations and understand the behavior of the function. In this article, we have used the method of factoring out the GCF of the coefficients and the GCF of the variables to factor the function. We have also used the method of grouping to factor the quadratic expression. The final factors of the function are x, (x - 3), (2x^2 + x - 3).

Applications

The factors of a polynomial function have many applications in mathematics and science. For example, they can be used to solve equations, understand the behavior of the function, and find the roots of the function.
