## Simplifying Algebraic Expressions

Algebraic expressions are mathematical statements that combine numbers and variables using mathematical operations. Simplifying an algebraic expression involves transforming it into an equivalent form that is easier to understand and work with. Here’s a step-by-step guide on how to simplify various types of algebraic expressions:

### 1. Combine Like Terms

- Identify terms that have the same variables and exponents.
- Add or subtract the coefficients of like terms.

### 4. Factoring Common Factors

- Find the greatest common factor (GCF) of all terms in the expression.
- Factor out the GCF as a product.
- Multiply the GCF by the remaining factors.

### Examples:

**a.** (3x + 5) + (2x – 7) = 5x – 2

**b.** 2(x – 4) – 3(x + 1) = -x – 10

**c.** (x + 2)(x – 3) = x^2 – x – 6

**d.** (2/3)x – (1/4) = (11/12)x – 1/4

**e.** (x^2y^3)^4 = x^8y^12

### Conclusion

Simplifying algebraic expressions is a fundamental skill in algebra. By following the steps outlined above, you can transform complex expressions into simpler forms, making them easier to understand and operate with. This skill is essential for solving more advanced algebraic equations and understanding mathematical concepts.
