Introduction

When it comes to dividing polynomials, there are several methods that can be used to simplify the process. One of the most common methods is long division, which involves dividing the highest degree term of the dividend by the highest degree term of the divisor. In this article, we will explore how to divide a polynomial using long division, and provide examples of how to apply this method to different types of polynomials.

Long Division of Polynomials

Long division of polynomials is a step-by-step process that involves dividing the highest degree term of the dividend by the highest degree term of the divisor. The process is similar to long division of numbers, but with polynomials, we need to consider the degree of each term. Here are the steps involved in long division of polynomials:

1. Divide the highest degree term of the dividend by the highest degree term of the divisor. This will give us the first term of the quotient.
2. Multiply the entire divisor by the first term of the quotient. This will give us a polynomial that we can subtract from the dividend.
3. Bring down the next term of the dividend. This will give us a new polynomial that we can repeat the process with.
4. Repeat steps 1-3 until we have used up all the terms of the dividend.
5. If there is a remainder, include it as a fraction.

Example 1: Dividing a Polynomial by a Linear Factor

Let's consider the polynomial $\left(-72v^3 + 92v^2 - 136v + 102\right)$ and divide it by the linear factor $(9v - 7)$. To do this, we will use long division.

Step 1: Divide the highest degree term of the dividend by the highest degree term of the divisor

The highest degree term of the dividend is $-72v^3$, and the highest degree term of the divisor is $9v$. Dividing $-72v^3$ by $9v$ gives us $-8v^2$.

Step 2: Multiply the entire divisor by the first term of the quotient

Multiplying the entire divisor $(9v - 7)$ by $-8v^2$ gives us $-72v^3 + 56v^2$.

Step 3: Bring down the next term of the dividend

The next term of the dividend is $92v^2$. We will bring this down to get a new polynomial: $-72v^3 + 92v^2 - 136v + 102$.

Step 4: Repeat steps 1-3

We will repeat the process with the new polynomial. Dividing $92v^2$ by $9v$ gives us $10.22v$. Multiplying the entire divisor $(9v - 7)$ by $10.22v$ gives us $92v^2 - 78.54v$. Subtracting this from the new polynomial gives us $-57.46v + 102$.

Step 5: Repeat steps 1-3

We will repeat the process with the new polynomial. Dividing $-57.46v$ by $9v$ gives us $-6.38$. Multiplying the entire divisor $(9v - 7)$ by $-6.38$ gives us $-57.42v + 45.66$. Subtracting this from the new polynomial gives us $-0.14v + 56.34$.

Step 6: Repeat steps 1-3

We will repeat the process with the new polynomial. Dividing $-0.14v$ by $9v$ gives us $-0.0156v$. Multiplying the entire divisor $(9v - 7)$ by $-0.0156v$ gives us $-0.14v + 0.0108$. Subtracting this from the new polynomial gives us $56.33$.

Step 7: Include the remainder as a fraction

Since we have used up all the terms of the dividend, we can include the remainder as a fraction. The remainder is $56.33$, which can be written as a fraction: $\frac{56.33}{1}$.

Conclusion

In this article, we have explored how to divide a polynomial using long division. We have provided an example of how to apply this method to a polynomial divided by a linear factor. We have also discussed how to include the remainder as a fraction if the polynomial does not divide evenly. Long division of polynomials is a powerful tool that can be used to simplify complex polynomials and solve equations.

Example 2: Dividing a Polynomial by a Quadratic Factor

Let's consider the polynomial $\left(-72v^3 + 92v^2 - 136v + 102\right)$ and divide it by the quadratic factor $(9v^2 - 7v)$. To do this, we will use long division.

Step 1: Divide the highest degree term of the dividend by the highest degree term of the divisor

The highest degree term of the dividend is $-72v^3$, and the highest degree term of the divisor is $9v^2$. Dividing $-72v^3$ by $9v^2$ gives us $-8v$.

Step 2: Multiply the entire divisor by the first term of the quotient

Multiplying the entire divisor $(9v^2 - 7v)$ by $-8v$ gives us $-72v^3 + 56v^2$.

Step 3: Bring down the next term of the dividend

The next term of the dividend is $92v^2$. We will bring this down to get a new polynomial: $-72v^3 + 92v^2 - 136v + 102$.

Step 4: Repeat steps 1-3

We will repeat the process with the new polynomial. Dividing $92v^2$ by $9v^2$ gives us $10.22$. Multiplying the entire divisor $(9v^2 - 7v)$ by $10.22$ gives us $92v^2 - 78.54v$. Subtracting this from the new polynomial gives us $-57.46v + 102$.

Step 5: Repeat steps 1-3

We will repeat the process with the new polynomial. Dividing $-57.46v$ by $9v$ gives us $-6.38$. Multiplying the entire divisor $(9v^2 - 7v)$ by $-6.38$ gives us $-57.42v + 45.66v$. Subtracting this from the new polynomial gives us $-11.34v + 56.34$.

Step 6: Repeat steps 1-3

We will repeat the process with the new polynomial. Dividing $-11.34v$ by $9v$ gives us $-1.26$. Multiplying the entire divisor $(9v^2 - 7v)$ by $-1.26$ gives us $-11.34v + 8.82v$. Subtracting this from the new polynomial gives us $47.52$.

Step 7: Include the remainder as a fraction

Since we have used up all the terms of the dividend, we can include the remainder as a fraction. The remainder is $47.52$, which can be written as a fraction: $\frac{47.52}{1}$.

Conclusion

In this article, we have explored how to divide a polynomial using long division. We have provided an example of how to apply this method to a polynomial divided by a quadratic factor. We have also discussed how to include the remainder as a fraction if the polynomial does not divide evenly. Long division of polynomials is a powerful tool that can be used to simplify complex polynomials and solve equations.

Example 3: Dividing a Polynomial by a Cubic Factor

Let's consider the polynomial $\left(-72v^3 + 92v^2 - 136v + 102\right)$ and divide it by the cubic factor $(9v^3 - 7v^2)$. To do this, we will use long division.

Step 1: Divide the highest degree term of the dividend by the highest degree term of the divisor

The highest degree term of the dividend is $-72v^3$, and the highest degree term of the divisor is $9v^3$. Dividing $-72v^3$ by $9v^3$ gives us $-8$.

Step 2: Multiply the entire divisor by the first term of the quotient

Multiplying the entire divisor $(9v^3 - 7v^2)$ by $-8$ gives us $-72v^3 + 56v^2$.

Step 3: Bring down the next term of the dividend

The next term of the dividend is $92v^2$. We will bring this down to get a new polynomial: $-72v^3 + 92v^2 - 136v + 102$.

Step 4: Repeat steps 1-3

We will repeat the process with the new polynomial. Dividing $92v^2$ by $9v^2$ gives us $10.22$. Multiplying the entire divisor $(9v^3 - 7v^2)$ by $10.22$ gives us $92v^2 - 78.54v^2$. Subtracting this from the new polynomial gives us $13.54v
