Introduction

Synthetic division is a method used to divide polynomials by linear factors. It is a powerful tool for simplifying complex polynomial expressions and is widely used in algebra and calculus. In this article, we will use synthetic division to divide the expression $\left(3m^3 - 14m^2 + 14m + 4\right)$ by the linear factor $(m + 2)$ .

The Process of Synthetic Division

Synthetic division involves a series of steps that are performed in a specific order. The process is as follows:

Write down the coefficients of the polynomial: The coefficients of the polynomial are the numbers that multiply the powers of the variable. In this case, the coefficients are 3, -14, 14, and 4.
Write down the root of the linear factor: The root of the linear factor is the number that is being divided out. In this case, the root is -2.
Bring down the first coefficient: The first coefficient is the first number in the list of coefficients. In this case, the first coefficient is 3.
Multiply the root by the first coefficient: Multiply the root by the first coefficient to get the next number in the list. In this case, -2 x 3 = -6.
Add the next coefficient to the result: Add the next coefficient to the result of the previous step. In this case, -6 + (-14) = -20.
Multiply the root by the result: Multiply the root by the result of the previous step to get the next number in the list. In this case, -2 x -20 = 40.
Add the next coefficient to the result: Add the next coefficient to the result of the previous step. In this case, 40 + 14 = 54.
Multiply the root by the result: Multiply the root by the result of the previous step to get the next number in the list. In this case, -2 x 54 = -108.
Add the last coefficient to the result: Add the last coefficient to the result of the previous step. In this case, -108 + 4 = -104.

The Result of Synthetic Division

The result of synthetic division is a new polynomial that is the result of dividing the original polynomial by the linear factor. In this case, the result is -104 + 54m - 20m^2 + 3m^3.
