## Introduction to Adding and Subtracting Polynomials Calculator

Adding and Subtracting Polynomials Calculator is an online tool that helps you to find the summation and difference of polynomial variables and you will understand how to add polynomials.

The adding polynomials calculator is used to **determine the polynomial variable** whose coefficient is added or subtracted with another variable of the same number of degrees in less than a minute.

## What are the Adding and Subtracting Polynomials?

Adding and subtracting polynomials is a mathematical expression with **two or more terms separated** by addition or subtraction.

This method is solved with the help of the arithmetic operation (addition, subtraction) of the same number of variables in a given polynomial equation. A polynomial variable is always present in a whole number only, and its power can not be negative, irrational, or a fraction term.

## Formula Behind Adding Polynomials Calculator:

A polynomial variable is a mathematical expression that consists of whole numbers and variables with different degree terms. The adding and subtracting polynomials calculator uses the following **notation** for solving the polynomial variables,

$$ a_0 x^n + a_1 x^{n-1} + a_2 x^{n-2} + …. + a_n x^0 $$

Whereas,

a0,a1,a2,a3,... represent the whole number

x^{n},x^{n-1},x^{n-2},x^{n-3},... is the x term of variable

n: number of degree of x variable

## Working Process of Add and Subtract Polynomials Calculator

The add polynomials calculator uses a simple method of adding and subtracting polynomials of the like terms of polynomial variables. First, it **arranges all the given polynomial variables** into a standard form before you add or subtract the given terms.

When you give the input value of polynomial variable problems in add and subtract functions calculator, it starts calculating the given similar variables terms.

### For Addition of Polynomials

In addition to polynomial variables, when you **add both equations** our tool uses a simple addition method. There is the only difference in polynomial addition is that it adds like terms variables only and unlike variable terms remain the same.

With that, a sign of polynomial variables also remains the same after summation as shown in the example solution of 5x-2+y +(-3y+5x+2).

### For Subtraction of Polynomial

For subtraction of polynomial variables, when you **subtract both polynomial equations** the sign of the second equation is multiple with (-)sign as shown in the below example -4x+7-(5x-3)=-4x+7-5x+3.

After multiplying the sign of the second algebraic expression is changed, then it subtracts the like terms only, and unlike remains unchanged. In subtraction of polynomial degree of variables remains the same as it was before the subtraction process.

Let's take an example with the solution to get a better understanding of the working process of adding and subtracting polynomials calculator.

## How to Add Polynomials - Example

The add and subtract polynomials calculator solves the problems easily but the necessity to solve manually is still there. So we are going to give you an example,

### Example 1:

Add the following polynomials:

$$ 5x - 2 + y \; and \; -3y + 5x + 2 $$

**Solution:**

$$ 5x - 2 + y + (-3y + 5x + 2) $$

$$ 5x + 5x + y - 3y - 2 + 2 $$

$$ 10x - 2y $$

### Example 2:

Simplify the following polynomials:

$$ -4x + 7 - (5x - 3) $$

**Solution:**

$$ -4x + 7 - (5x - 3) $$

$$ -4x + 7 - 5x + 3 $$

$$ -9x + 10 $$
