Q: How do I simplify an algebraic expression?
A: To simplify an algebraic expression, follow these steps:
- Combine like terms: Like terms are terms that have the same variable and exponent. For example, 2x and 3x are like terms, as they both have the variable x and the same exponent (1).
- Rearrange the terms: Rearrange the terms in the expression to group like terms together.
- Simplify the expression: Simplify the expression by combining like terms and rearranging the terms.
Q: What are like terms?
A: Like terms are terms that have the same variable and exponent. For example, 2x and 3x are like terms, as they both have the variable x and the same exponent (1).
Q: How do I identify like terms in an algebraic expression?
A: To identify like terms in an algebraic expression, look for terms that have the same variable and exponent. For example, in the expression 2x + 3x, the terms 2x and 3x are like terms, as they both have the variable x and the same exponent (1).
Q: Can I simplify an algebraic expression with variables of different exponents?
A: Yes, you can simplify an algebraic expression with variables of different exponents. However, you cannot combine terms with variables of different exponents. For example, in the expression 2x^2 + 3x, you cannot combine the terms 2x^2 and 3x, as they have different exponents.
Q: How do I simplify an algebraic expression with negative coefficients?
A: To simplify an algebraic expression with negative coefficients, follow the same steps as before. However, when combining like terms, make sure to combine the negative coefficients correctly. For example, in the expression -2x + 3x, the terms -2x and 3x are like terms, as they both have the variable x and the same exponent (1). When combining these terms, you get 1x, which is equal to x.
Q: Can I simplify an algebraic expression with fractions?
A: Yes, you can simplify an algebraic expression with fractions. However, you need to follow the rules of fraction arithmetic, such as multiplying the numerators and denominators of the fractions. For example, in the expression 1/2x + 1/3x, you need to find a common denominator, which is 6. Then, you can combine the fractions by adding the numerators and keeping the common denominator. The result is 5/6x.
Q: How do I simplify an algebraic expression with parentheses?
A: To simplify an algebraic expression with parentheses, follow the order of operations (PEMDAS):
- Parentheses: Evaluate the expressions inside the parentheses first.
- Exponents: Evaluate any exponents next.
- Multiplication and Division: Evaluate any multiplication and division operations from left to right.
- Addition and Subtraction: Finally, evaluate any addition and subtraction operations from left to right.
