Why Use an Adding and Subtracting Polynomials Worksheet?
When learning algebra, it’s one thing to grasp the theory behind polynomials, but another
to apply that knowledge effectively. Worksheets specifically designed for adding and
subtracting polynomials help bridge this gap by offering targeted practice. By working
through these exercises, learners can:
Understand combining like terms.
Practice aligning terms correctly.

Build confidence in handling variables and coefficients.
Moreover, these worksheets serve as excellent revision tools or homework assignments,
making abstract concepts tangible.
Understanding the Basics: What Are Polynomials?
Before diving into addition and subtraction, it helps to clarify what polynomials are. A
polynomial is an expression consisting of variables and coefficients, combined using only
addition, subtraction, multiplication, and non-negative integer exponents.
For example:
\(3x^2 + 2x - 5\)
\(7y^3 - 4y + 1\)
Polynomials vary in degree, depending on the highest exponent of the variable. Knowing
this helps when combining like terms during addition or subtraction.
Key Terms to Remember
**Term:** Each part of the polynomial separated by plus or minus signs (e.g.,
\(3x^2\), \(-5\))
**Coefficient:** The numerical factor in a term (e.g., 3 in \(3x^2\))
**Variable:** The letter representing an unknown quantity (e.g., \(x\))
**Degree:** The highest exponent in the polynomial (e.g., 2 in \(3x^2\))
How to Add Polynomials: Step-by-Step
Adding polynomials may seem intimidating at first, but it follows a simple and logical
process. Here’s a breakdown:
Step 1: Write Polynomials in Standard Form
Make sure each polynomial is arranged in descending order of degrees. This helps when
aligning like terms.
Step 2: Identify Like Terms
Like terms have the same variable raised to the same power. For example, \(4x^2\) and
\(-7x^2\) are like terms, while \(4x^2\) and \(4x\) are not.
Step 3: Add Coefficients of Like Terms
Combine coefficients by addition while keeping the variable and exponent unchanged.
Step 4: Write the Resulting Polynomial
After combining, write down the simplified polynomial expression.
Example
Add \(3x^2 + 5x - 2\) and \(4x^2 - 3x + 7\):
\[
(3x^2 + 5x - 2) + (4x^2 - 3x + 7) = (3x^2 + 4x^2) + (5x - 3x) + (-2 + 7) = 7x^2 + 2x +
\]
Subtracting Polynomials Made Simple
Subtracting polynomials follows a process similar to addition with a crucial
difference—distributing the negative sign.
Step 1: Write Both Polynomials in Standard Form
As with addition, arrange terms by descending degree.
Step 2: Distribute the Negative Sign
When subtracting the second polynomial, apply the negative sign to each term inside the
parentheses.
Step 3: Combine Like Terms by Subtracting Coefficients
Add the coefficients of like terms, remembering the negative sign has been distributed.
Step 4: Simplify and Write the Result
Present the final polynomial after combining.
Example
Subtract \(2x^3 - 4x + 6\) from \(5x^3 + 3x - 1\):
\[
(5x^3 + 3x - 1) - (2x^3 - 4x + 6) = 5x^3 + 3x - 1 - 2x^3 + 4x - 6 = (5x^3 - 2x^3) + (3x
+ 4x) + (-1 - 6) = 3x^3 + 7x - 7
\]
