Here is a detailed guide on how to add algebraic expressions:
Adding Algebraic Expressions
- **Identify Like Terms**: Before adding algebraic expressions, you need to identify like terms. Like terms are terms that have the same variables raised to the same power. For example, 3x and 5x are like terms because they both have the variable x raised to the power of 1.
- **Combine Like Terms**: Once you have identified the like terms in the algebraic expressions, you can combine them by adding or subtracting their coefficients. For example, to add 3x and 5x, you simply add their coefficients to get 8x.
- **Maintain the Variables**: When adding algebraic expressions, it is important to maintain the variables and their exponents. Make sure to only add or subtract the coefficients of like terms while keeping the variables the same.
- **Example**: Let's say you have the expressions 2x^2 + 3x - 4 and -x^2 + 5x + 2. To add these expressions, first identify the like terms. In this case, the like terms are the terms with x^2, x, and the constant terms. Then, combine the coefficients of the like terms to get the final result.
- **Final Result**: After combining the like terms in the given algebraic expressions, you will get the final result of adding the two expressions.
By following these steps, you can effectively add algebraic expressions. It is essential to correctly identify like terms and combine them systematically to arrive at the accurate sum of the expressions.
