Many students often struggle with algebra, especially when it comes to the fundamentals like combining like terms. Yet, understanding and practicing this core concept is essential for mastering algebraic operations. To help simplify algebra learning, we offer a series of free Combine Like Terms worksheets that can turn complex mathematical expressions into something more manageable for students of all levels.
Why Learn to Combine Like Terms?
Before diving into how you can simplify algebraic expressions, let’s understand why learning to combine like terms is crucial:
- Foundation for Algebra: Like term combinations are the building blocks for more complex algebraic operations.
- Simplify Problems: Combining like terms helps to reduce the complexity of equations, making problem-solving more straightforward.
- Preparation for Higher Math: Mastery of this skill is beneficial for advanced mathematics topics like calculus and statistics.
How to Combine Like Terms?
Here are the steps to combine like terms:
- Identify Like Terms: Like terms are expressions that have the same variables raised to the same power. For example, 3x and 5x are like terms because they both contain x.
- Combine the Coefficients: Add or subtract the coefficients (numbers in front of the variable) while keeping the variable and its exponent the same. For example, combining 3x + 5x results in 8x.
- Write the Result: Place the combined term in its proper place within the expression.
Sample Exercise
Consider the following expression: 6y + 3y - 7 + y^2 - 2y
- Like terms here are 6y, 3y, and -2y.
- Combine these to get (6 + 3 - 2)y = 7y.
- The variable y^2 and constant -7 remain as they are because they have no like terms.
- The final result is y^2 + 7y - 7.
📚 Note: Remember to only combine terms that have the same variable(s) with the same exponents. Terms with different variables or different exponents are not considered like terms and should not be combined.
