Simplifying Algebraic Expressions: (a^2b–5ab+2ab^2)+(–4a^2b+3ab+5ab^2)
This article will guide you through simplifying the algebraic expression: (a^2b–5ab+2ab^2)+(–4a^2b+3ab+5ab^2).
Understanding the Basics
Before we start simplifying, let's understand a few key points about algebraic expressions:
- Like Terms: Terms with the same variables raised to the same powers are considered like terms. For example,
3ab
and-5ab
are like terms, but2ab^2
and3ab
are not. - Combining Like Terms: We can add or subtract only like terms. When combining like terms, we simply add or subtract their coefficients.
Simplifying the Expression
-
Identify Like Terms:
- a^2b:
a^2b
and-4a^2b
are like terms. - ab:
-5ab
and3ab
are like terms. - ab^2:
2ab^2
and5ab^2
are like terms.
- a^2b:
-
Combine Like Terms:
- a^2b:
a^2b - 4a^2b = -3a^2b
- ab:
-5ab + 3ab = -2ab
- ab^2:
2ab^2 + 5ab^2 = 7ab^2
- a^2b:
-
Write the Simplified Expression: The simplified expression is -3a^2b - 2ab + 7ab^2.
Conclusion
By identifying like terms and combining them, we have successfully simplified the expression. The process of combining like terms is a fundamental concept in algebra and is essential for solving more complex algebraic equations and inequalities.
