Introduction
Algebraic expressions are a fundamental concept in mathematics, and simplifying them is a crucial skill to master. In this article, we will focus on simplifying a given algebraic expression by factoring out common terms. We will use the expression as an example and break it down into manageable steps.
Understanding the Expression
The given expression is . At first glance, it may seem complex, but by breaking it down, we can simplify it. The expression consists of several terms, including constants and variables.
Constants and Variables
- Constants: These are numbers that do not change value. In the given expression, the constants are 4, 10, and -2.
- Variables: These are letters or symbols that represent unknown values. In the given expression, the variable is b.
Simplifying the Expression
To simplify the expression, we need to combine like terms. Like terms are terms that have the same variable raised to the same power.
Combining Like Terms
The expression can be rewritten as:
Combine the like terms:
Factoring the Expression
Now that we have simplified the expression, we can factor it out. Factoring an expression means expressing it as a product of simpler expressions.
Factoring Out Common Terms
The expression can be factored out as:
This is because 3 is a common factor of both terms.

Introduction
In our previous article, we discussed how to simplify algebraic expressions by combining like terms and factoring out common terms. In this article, we will answer some frequently asked questions about simplifying algebraic expressions.
Q&A
Q: What are like terms?
A: Like terms are terms that have the same variable raised to the same power. For example, 2x and 4x are like terms because they both have the variable x raised to the power of 1.
Q: How do I combine like terms?
A: To combine like terms, add or subtract the coefficients of the like terms. For example, 2x + 4x = (2 + 4)x = 6x.
Q: What is the distributive property?
A: The distributive property is a rule that states that a single term can be multiplied by each term in a parentheses. For example, 3(x + 2) = 3x + 6.
Q: How do I factor out common terms?
A: To factor out common terms, look for terms that have a common factor. For example, 6x + 12 can be factored out as 6(x + 2).
Q: What is the difference between simplifying and factoring?
A: Simplifying an expression means combining like terms and reducing the number of terms. Factoring an expression means expressing it as a product of simpler expressions.
Q: Can I simplify an expression that has variables with exponents?
A: Yes, you can simplify an expression that has variables with exponents. For example, 2x^2 + 4x^2 = 6x^2.
Q: How do I handle negative coefficients?
A: When simplifying an expression with negative coefficients, remember to change the sign of the coefficient when combining like terms. For example, -2x + 4x = (2 - 4)x = -2x.
Q: Can I simplify an expression that has fractions?
A: Yes, you can simplify an expression that has fractions. For example, 1/2x + 1/4x = (2/4)x + (1/4)x = (3/4)x.
