Adding and Subtracting Polynomials Worksheet | Algebra 1 Practice

A worksheet on adding and subtracting polynomials. The students are required to add or subtract given polynomials, find the missing terms in given additions or subtractions between polynomials, evaluate polynomials at a point and find a polynomial that when added to another polynomial results a given sum. Detailed solutions are included.

Help your students master operations with algebraic expressions using this comprehensive, ready-to-print Adding and Subtracting Polynomials Worksheet!

This resource goes far beyond basic, repetitive equations. It features a carefully scaffolded progression that challenges students to distribute brackets, combine multi-variable terms, and apply deductive reasoning across multiple unique question styles. Whether you need a rigorous lesson companion, independent homework assignment, unit revision, or a reliable cover plan, this worksheet is completely ready to print and use immediately.

What’s Included in This Resource?

• Core Skill Practice – 12 targeted addition and subtraction problems featuring expressions up to the 4th degree, signed integers, fractions, and multi-variable structures (such as terms containing both x and y).
• Missing-Term Logic Puzzles – Fill-in-the-blank box challenges that force students to work backward to determine the missing polynomial terms, testing true mastery of algebraic operations.
• Polynomial Relationships – Guided algebraic tasks requiring students to manipulate given polynomial expressions through addition, negation, and subtraction.
• Introduction to Function Notation – High-level challenges where students evaluate specific inputs for distinct polynomial functions.
• Working Backward Word Problems – Deductive reasoning challenges that require students to find the exact polynomial needed to reach a given target sum.

Key Skills Covered

• Combining like terms with higher-degree polynomials
• Operating with multi-variable structures (e.g., xy terms)
• Distributing negative signs correctly across subtraction groupings and expanding brackets
• Solving for missing polynomial components
• Evaluating functions using standard function notation
