Introduction

Polynomial division is a fundamental concept in algebra that involves dividing one polynomial by another. It is an essential tool for simplifying complex expressions and solving equations. In this article, we will explore the process of dividing polynomials, focusing on the division of a cubic polynomial by a linear polynomial.

The Division Process

To divide a polynomial, we need to follow a series of steps. The process involves dividing the highest degree term of the dividend by the highest degree term of the divisor, and then multiplying the entire divisor by the result. We then subtract the product from the dividend and repeat the process until we have a remainder that is of lower degree than the divisor.

Dividing the Polynomial

Let's apply the division process to the given polynomial:

$$\frac{6x^3 + 11x^2 - 4x - 4}{3x - 2}$$

We will divide the cubic polynomial by the linear polynomial $3x - 2$. To start, we divide the highest degree term of the dividend, $6x^3$, by the highest degree term of the divisor, $3x$. This gives us $2x^2$.

Step 1: Divide the Highest Degree Term

$$\frac{6x^3}{3x} = 2x^2$$

Step 2: Multiply the Divisor by the Result

We multiply the entire divisor, $3x - 2$, by the result, $2x^2$. This gives us:

$$2x^2(3x - 2) = 6x^3 - 4x^2$$

Step 3: Subtract the Product from the Dividend

We subtract the product from the dividend:

$$6x^3 + 11x^2 - 4x - 4 - (6x^3 - 4x^2) = 15x^2 - 4x - 4$$

Step 4: Repeat the Process

We repeat the process, dividing the highest degree term of the new dividend, $15x^2$, by the highest degree term of the divisor, $3x$. This gives us $5x$.

Step 5: Multiply the Divisor by the Result

We multiply the entire divisor, $3x - 2$, by the result, $5x$. This gives us:

$$5x(3x - 2) = 15x^2 - 10x$$

Step 6: Subtract the Product from the Dividend

We subtract the product from the dividend:

$$15x^2 - 4x - 4 - (15x^2 - 10x) = 6x - 4$$

Step 7: Repeat the Process

We repeat the process, dividing the highest degree term of the new dividend, $6x$, by the highest degree term of the divisor, $3x$. This gives us $2$.

Step 8: Multiply the Divisor by the Result

We multiply the entire divisor, $3x - 2$, by the result, $2$. This gives us:

$$2(3x - 2) = 6x - 4$$

Step 9: Subtract the Product from the Dividend

We subtract the product from the dividend:

$$6x - 4 - (6x - 4) = 0$$

The Final Result

We have now completed the division process. The final result is:

$$2x^2 + 5x + 2$$
