## What Is Polynomial Long Division?

Polynomial long division is an algebraic method for dividing one polynomial by another of the same or lesser degree. This technique mirrors the traditional long division process used for numerical calculations, with the distinct difference being the use of variables and coefficients, not just numbers.

## How to Do Polynomial Long Division?

Polynomial long division can be performed using the following steps:

**Arrange the Polynomial:**Write the dividend and the divisor in descending order. This means that the highest power of the variable is written first and then the lower powers are in descending order.**Divide the First Terms:**Divide the first term (the highest degree term) of the dividend by the first term of the divisor. Write the result above the line as the first term of the quotient.**Multiply and Subtract:**Multiply the entire divisor by the first term of the quotient. Write the result under the dividend. Subtract this from the original dividend to get a new polynomial.**Repeat the Process:**Consider the new polynomial as the new dividend. Again, divide this new dividend's first term by the divisor's first term. Write this result as the next term of the quotient. Multiply the divisor by the new term of the quotient, write under the new dividend, and subtract.**Keep Going:**Continue the process until the degree of the remainder (new dividend) is less than that of the divisor.**Get the Result:**The polynomial you obtain above the line is the quotient, and the final remainder is what's left after the last subtraction step. If there's no remainder, the divisor evenly divides the original dividend.

Let's examine an example.

Suppose we have the following division problem: $$$\frac{2x^3-2x^2+3x-3}{x-1}$$$.

The process of long division would proceed as follows:

- Divide the highest degree term in the dividend $$$\left(2x^3\right)$$$ by the highest degree term in the divisor $$$\left(x\right)$$$. This gives us the first term of the quotient, namely, $$$\frac{2x^3}{x}=2x^2$$$.
- Multiply the divisor $$$x-1$$$ by the first term of the quotient $$$\left(2x^2\right)$$$ and subtract the result from the dividend. This gives us a new dividend $$$2x^3-2x^2+3x-3-2x^2(x-1)=2x^3-2x^2+3x-3-2x^3+2x^2=3x-3$$$.
- Repeat the process with the new dividend, dividing the highest degree term $$$\left(3x\right)$$$ by the highest degree term in the divisor $$$\left(x\right)$$$, which gives us $$$\frac{3x}{x}=3$$$. Multiply the divisor by $$$3$$$ and subtract from the new dividend, which gives us a remainder of $$$3x-3-3(x-1)=3x-3-3x+3=0$$$.

So the result of the division is $$$2x^2+3$$$.

### FAQ

#### What is the formula for polynomial division?

While there isn't a specific formula for polynomial division, there is a method that can be called "divide, multiply, subtract, bring down, and repeat."

#### What are the two methods to divide polynomials?

There are two primary methods for dividing polynomials: long division and synthetic division. Polynomial long division is similar to the long division of numbers and can be used in all scenarios. Synthetic division is a shortcut method that works only when dividing by a linear factor $$$x - a$$$.
