How do you Simplify StepbyStep?
To simplify an algebraic expression or mathematical equation, follow these stepbystep guidelines:
 Combine Like Terms: Identify terms with similar variables and exponents and combine them using the rules of addition or subtraction.
 Remove Parentheses: Apply the distributive property to eliminate parentheses and simplify the expression further.
 Combine Constants: Add or subtract constants to simplify the equation.
 Simplify Exponents: Use the laws of exponents to simplify expressions involving powers.
 Simplify Fractions: Reduce fractions to their simplest form by canceling out common factors in the numerator and denominator.
By following these steps, you can transform complex expressions into more manageable forms, making mathematical calculations smoother and more accurate.
Rules for Simplifying Algebraic Expressions
When simplifying algebraic expressions, it is crucial to keep a few rules in mind. These rules help maintain consistency and accuracy throughout the simplification process:
 Addition and Subtraction: Only combine terms with the same variables and exponents. For example, 3x + 2x can be simplified to 5x, but 3x + 2y cannot be further simplified.
 Multiplication: Multiply coefficients and combine variables with the same exponents. For instance, 2xy * 3xy simplifies to 6x²y².
 Division: Divide coefficients and subtract exponents when dividing like terms. For instance, (6x³) / (3x²) simplifies to 2x.
 Exponents: Apply the laws of exponents, such as multiplying exponents when raising a power to another power or dividing exponents when dividing powers with the same base.
By adhering to these rules, simplifying algebraic expressions becomes a systematic and straightforward process.
Simplifying Fractions
One aspect of simplification that often arises is simplifying fractions. To simplify a fraction, divide the numerator and denominator by their greatest common divisor (GCD) or greatest common factor (GCF). The GCD is the largest number that divides evenly into both the numerator and denominator.
For example, consider the fraction 24/36. The GCD of 24 and 36 is 12. Dividing both the numerator and denominator by 12 yields 2/3. Thus, 24/36 simplifies to 2/3, which is its simplest form.
Simplifying fractions is particularly useful when working with ratios, proportions, and other mathematical concepts that involve fractions. It helps express fractions in their most reduced form, making them easier to work with and compare.
Simplifying Mathematical Expressions
Mathematical expressions can involve various components, such as constants, variables, operators, and exponents. Simplifying these expressions is crucial for gaining a deeper understanding of their structure and solving mathematical problems efficiently.
By applying the rules mentioned earlier and following stepbystep procedures, complex mathematical expressions can be simplified into concise and workable forms. This simplification allows for better comprehension and aids in the manipulation and manipulation of expressions to achieve desired results.
Simplifying Expressions with Exponents
Expressions involving exponents often appear in mathematical equations, and simplifying them can help reduce complexity. The laws of exponents guide the simplification process for such expressions. These laws include:
 Product Rule: When multiplying two exponents with the same base, add their exponents. For example, x² * x³ simplifies to x⁵.
 Quotient Rule: When dividing two exponents with the same base, subtract the exponents. For instance, x⁵ / x² simplifies to x³.
 Power Rule: When raising an exponent to another power, multiply the exponents. For example, (x²)³ simplifies to x⁶.
 Zero Exponent Rule: Any nonzero number raised to the power of zero equals 1. For instance, x⁰ simplifies to 1.
By applying these rules, expressions involving exponents can be simplified, aiding in efficient calculations and problemsolving.
Simplifying Expressions with Distributive Property
The distributive property is a fundamental rule in mathematics that enables us to simplify expressions by removing parentheses and distributing a value across terms inside them. This property states that for any real numbers a, b, and c:
a(b + c) = ab + ac
By using the distributive property, we can simplify expressions involving addition or subtraction within parentheses. This simplification helps streamline equations and makes them more accessible to work with.
Simplifying Expressions with Fractions
Working with expressions containing fractions may seem intimidating, but simplifying them can bring clarity to the equation. To simplify expressions with fractions, we must combine fractions with common denominators and then perform the necessary arithmetic operations.
For example, consider the expression (3/4)x + (1/2)x. To simplify this expression, we need to find the common denominator of 4 and 2, which is 4. Multiplying the first fraction by 1 (in the form of 2/2) and the second fraction by 2/2 yields (6/8)x + (4/8)x. Combining like terms, we obtain (10/8)x or, when simplified further, (5/4)x.
Simplifying expressions with fractions allows for better comprehension and easier manipulation of equations, making mathematical calculations more manageable.

Simplify the expression 4(2x + 3y) – 2(5x – y).
 Solution: Using the distributive property, we obtain 8x + 12y – 10x + 2y. Combining like terms, we have 2x + 14y.
These examples demonstrate how simplification allows us to condense complex expressions into simpler and more manageable forms, aiding in efficient problemsolving.
