What is the completely factored form of 3x^5 – 7x^4 + 6x^2 – 14x?

## Introduction to Polynomial Factoring

Polynomial factoring is an important concept in algebra that involves breaking down a polynomial equation into its simplest and most basic components. The completely factored form of a polynomial is the expression of the polynomial as a product of its irreducible factors. This process helps simplify complex equations and allows for easier analysis and solution of polynomial equations.

## Understanding the Polynomial 3x^5 – 7x^4 + 6x^2 – 14x

The given polynomial 3x^5 – 7x^4 + 6x^2 – 14x can be factored by finding the greatest common factor (GCF) and then using techniques such as factoring by grouping, difference of squares, or sum/difference of cubes. In this case, we will explore the completely factored form of the given polynomial using various methods to demonstrate the process of factoring.

## Factoring by Finding the Greatest Common Factor (GCF)

The first step in factoring the polynomial 3x^5 – 7x^4 + 6x^2 – 14x is to find the greatest common factor (GCF) of the terms in the polynomial. The GCF is the largest expression that divides all the terms in the polynomial evenly. In this case, the GCF of the polynomial is x, as it is the highest power of x that can be divided into each term.

By factoring out the GCF of x from each term, we get:

3x^5 – 7x^4 + 6x^2 – 14x = x(3x^4 – 7x^3 + 6x – 14)

## Factoring by Grouping

After factoring out the GCF, we can then use the technique of factoring by grouping to further simplify the polynomial. This method involves grouping the terms in the polynomial in pairs and factoring each pair separately.

In this case, we can group the terms as follows:

(3x^4 – 7x^3) + (6x – 14)

Now, we can factor each pair separately:

x(3x^4 – 7x^3) + 2(3x – 7)

At this point, we notice that both pairs have a common factor that can be factored out. Therefore, we factor out the common factors from each pair:

x^2(3x^3 – 7) + 2(3x – 7)

After factoring out the common factors, we can see that the binomial expressions inside the parentheses are the same. This allows us to further simplify the polynomial by factoring out the common binomial factor:

(x^2 + 2)(3x – 7)

## Completely Factored Form of the Polynomial

After factoring by finding the greatest common factor and using the technique of factoring by grouping, we have arrived at the completely factored form of the polynomial 3x^5 – 7x^4 + 6x^2 – 14x:

3x^5 – 7x^4 + 6x^2 – 14x = x(x^2 + 2)(3x – 7)

## Conclusion

Understanding the completely factored form of the polynomial 3x^5 – 7x^4 + 6x^2 – 14x involves a step-by-step process of factoring the polynomial using techniques such as finding the greatest common factor and factoring by grouping. By breaking down the polynomial into its irreducible factors, we are able to simplify the equation and gain insight into its properties and behavior. Factoring polynomials is an essential skill in algebra and is often used in solving polynomial equations and analyzing mathematical models.
