Simplifying Expressions: 2x * 3x

Understanding how to simplify algebraic expressions is a fundamental skill in mathematics. Let's explore the expression 2x * 3x and break down the process of simplifying it.

Understanding the Basics:

• Variables: 'x' in this expression represents an unknown value.
• Coefficients: The numbers 2 and 3 are the coefficients, multiplying the variable 'x'.

Simplifying the Expression:

1. Identify like terms: Both terms in the expression have the variable 'x'.
2. Multiply the coefficients: 2 * 3 = 6
3. Multiply the variables: x * x = x²

The Result:

2x * 3x = 6x²

Why does x * x equal x²?

This is based on the concept of exponents. When a variable is multiplied by itself, we indicate that with an exponent. In this case, 'x' is multiplied by itself once, so the exponent is 2, resulting in x².

Practical Example:

Imagine you have two rectangles with lengths of 2x and 3x. To find the area of a rectangle, you multiply the length and width. In this case:

Area = 2x * 3x = 6x²

Therefore, the area of the rectangle is represented by the expression 6x².

Key Takeaways:

• When multiplying terms with the same variable, multiply the coefficients and add the exponents of the variables.
• Simplifying expressions makes them easier to work with and understand.
• The concept of exponents plays a crucial role in algebraic simplification.
