Combine Like Terms in Pre-Algebra: Pre Algebra Combine Like Terms Worksheet Answer Key
In algebra, combining like terms is a fundamental operation that involves simplifying algebraic expressions by grouping and adding or subtracting terms with the same variable and exponent.
Combining like terms is crucial for simplifying complex algebraic expressions, making them easier to solve and understand. It helps eliminate redundancy and unnecessary terms, leading to more efficient calculations and problem-solving.
Methods and Procedures
To combine like terms, follow these steps:
- Identify like terms: Terms with the same variable and exponent are considered like terms.
- Group like terms: Place like terms together within the expression.
- Combine coefficients: Add or subtract the coefficients of like terms with the same sign. If the signs are different, subtract the smaller coefficient from the larger one.
- Simplify the expression: Write the combined terms in their simplest form.
Practice Exercises
- Combine: 3x + 2x
- Simplify: 5y – 3y + 7
- Combine: 4a^2 – 2a^2 + 6a
