Mastering the Art of Combining Like Terms: A Comprehensive Guide
Combining like terms is a fundamental concept in algebra, and it’s essential to grasp this skill to succeed in math and problem-solving. In this article, we’ll delve into the world of like terms, explore the concept, and provide a worksheet with answers and solutions to help you practice and reinforce your understanding.
What are Like Terms?
Like terms are terms that have the same variable(s) raised to the same power. In other words, like terms are terms that have the same base and exponent. For example, 2x and 3x are like terms because they both have the variable x raised to the power of 1. On the other hand, 2x and 2y are not like terms because they have different variables.
Why Combine Like Terms?
Combining like terms is essential in algebra because it helps simplify expressions and equations. By combining like terms, you can:
- Simplify complex expressions
- Make equations easier to solve
- Identify patterns and relationships between variables
How to Combine Like Terms
Combining like terms is a straightforward process. Here are the steps:
- Identify the like terms in an expression or equation.
- Add or subtract the coefficients of the like terms.
- Write the result as a single term.
For example, let’s combine the like terms in the expression: 2x + 3x + 4y
- Identify the like terms: 2x and 3x
- Add the coefficients: 2 + 3 = 5
- Write the result: 5x + 4y
Combining Like Terms Worksheet
Now that you’ve learned the concept of combining like terms, it’s time to practice! Here’s a worksheet with 10 problems to help you reinforce your understanding.
| Problem | Solution |
|---|---|
| 1. 2x + 3x + 4y | 5x + 4y |
| 2. 4x - 2x + 3y | 2x + 3y |
| 3. 2y + 3y - 4x | 5y - 4x |
| 4. x + 2x + 3y | 3x + 3y |
| 5. 3x - 2x + 2y | x + 2y |
| 6. 2y + 4y - 3x | 6y - 3x |
| 7. 4x + 2x + 5y | 6x + 5y |
| 8. x - 3x + 2y | -2x + 2y |
| 9. 3y + 2y - 4x | 5y - 4x |
| 10. 2x + 5x - 3y | 7x - 3y |
📝 Note: Make sure to identify the like terms correctly and combine them by adding or subtracting their coefficients.
