Introduction

Polynomial division is a fundamental concept in algebra, and it plays a crucial role in solving polynomial equations. In this article, we will learn how to divide the polynomial x4βˆ’3x2βˆ’10x+6x^4 - 3x^2 - 10x + 6 by x2+2x+3x^2 + 2x + 3. We will use the long division method to perform this division.

The Long Division Method

The long division method is a step-by-step process that involves dividing the polynomial by the divisor. The process involves the following steps:

  1. Divide the leading term of the dividend by the leading term of the divisor.
  2. Multiply the entire divisor by the result obtained in step 1.
  3. Subtract the product obtained in step 2 from the dividend.
  4. Bring down the next term of the dividend.
  5. Repeat steps 1-4 until the degree of the remainder is less than the degree of the divisor.

Divide the Polynomial

To divide the polynomial x4βˆ’3x2βˆ’10x+6x^4 - 3x^2 - 10x + 6 by x2+2x+3x^2 + 2x + 3, we will use the long division method.

Step 1: Divide the Leading Term

The leading term of the dividend is x4x^4, and the leading term of the divisor is x2x^2. We will divide x4x^4 by x2x^2 to obtain x2x^2.

Step 2: Multiply the Divisor

We will multiply the entire divisor x2+2x+3x^2 + 2x + 3 by x2x^2 to obtain x4+2x3+3x2x^4 + 2x^3 + 3x^2.

Step 3: Subtract the Product

We will subtract the product obtained in step 2 from the dividend x4βˆ’3x2βˆ’10x+6x^4 - 3x^2 - 10x + 6 to obtain βˆ’2x3βˆ’3x2βˆ’10x+6-2x^3 - 3x^2 - 10x + 6.

Step 4: Bring Down the Next Term

We will bring down the next term of the dividend, which is βˆ’10x-10x.

Step 5: Repeat the Process

We will repeat the process by dividing the leading term of the new dividend βˆ’2x3βˆ’3x2βˆ’10x+6-2x^3 - 3x^2 - 10x + 6 by the leading term of the divisor x2+2x+3x^2 + 2x + 3. We will obtain βˆ’2x-2x.

Step 6: Multiply the Divisor

We will multiply the entire divisor x2+2x+3x^2 + 2x + 3 by βˆ’2x-2x to obtain βˆ’2x3βˆ’4x2βˆ’6x-2x^3 - 4x^2 - 6x.

Step 7: Subtract the Product

We will subtract the product obtained in step 6 from the new dividend βˆ’2x3βˆ’3x2βˆ’10x+6-2x^3 - 3x^2 - 10x + 6 to obtain x2βˆ’4x+6x^2 - 4x + 6.

Step 8: Bring Down the Next Term

We will bring down the next term of the new dividend, which is 66.

Step 9: Repeat the Process

Step 10: Multiply the Divisor

We will multiply the entire divisor x2+2x+3x^2 + 2x + 3 by 11 to obtain x2+2x+3x^2 + 2x + 3.

Step 11: Subtract the Product

We will subtract the product obtained in step 10 from the new dividend x2βˆ’4x+6x^2 - 4x + 6 to obtain βˆ’6x+3-6x + 3.

Step 12: Bring Down the Next Term

We will bring down the next term of the new dividend, which is 00.
