In the realm of algebra, equations are the fundamental building blocks that help us solve complex problems. This article focuses on simplifying and solving the expression 4x2 3x2. Whether you're a student or a professional dealing with algebra, understanding this concept is crucial. Let's delve into the details step-by-step.
Introduction to Algebraic Expressions
Algebraic expressions are combinations of variables, constants, and operators. Variables represent unknown values, and constants are fixed values. In the expression 4x2 3x2, x2 is the variable, and the coefficients 4 and 3 are the constants.
Understanding Polynomial Addition
The expression 4x2 3x2 can be simplified by combining like terms. Like terms are terms that have the same variables raised to the same powers. In this case, both 4x2 and 3x2 have the same variable (x) raised to the same power (2).
Step 1: Identify the Like Terms
The first step in simplifying the expression is to identify the like terms. Here, 4x2 and 3x2 are the like terms because they both have the variable x2.
Step 2: Add the Coefficients
Once the like terms are identified, the next step is to add the coefficients. The coefficients for 4x2 are 4, and for 3x2 are 3. Adding these coefficients gives us:
4 3 7
Step 3: Combine the Like Terms
Now, we combine the like terms by multiplying the resulting coefficient by the variable:
7x2
Conclusion
Thus, the simplified form of the expression 4x2 3x2 is 7x2. This process of simplifying and solving algebraic expressions is essential in many mathematical and scientific domains. Understanding these basics can help you tackle more complex equations and problems in the future.
