Simplifying Polynomial Expressions: (8a^5 - 4) + (3a^5 + a - 2)

This article will guide you through the process of simplifying the polynomial expression (8a^5 - 4) + (3a^5 + a - 2).

Understanding the Basics

Before we dive into simplification, let's refresh our understanding of some key terms:

  • Polynomial: A mathematical expression consisting of variables and coefficients, combined using addition, subtraction, and multiplication, where exponents can only be non-negative integers.
  • Terms: The individual parts of a polynomial separated by addition or subtraction signs.
  • Like Terms: Terms that have the same variable(s) raised to the same powers.

Simplifying the Expression

  1. Remove parentheses: Since we are adding the two polynomials, the parentheses don't affect the order of operations.

    (8a^5 - 4) + (3a^5 + a - 2) = 8a^5 - 4 + 3a^5 + a - 2

  2. Combine like terms: Identify terms with the same variables and exponents.

    • a^5 terms: 8a^5 + 3a^5 = 11a^5
    • a terms: + a (this is the only term with 'a' to the power of 1)
    • Constant terms: -4 - 2 = -6
  3. Write the simplified expression: Combine the simplified terms in descending order of their exponents.

    11a^5 + a - 6

Conclusion

Therefore, the simplified form of the expression (8a^5 - 4) + (3a^5 + a - 2) is 11a^5 + a - 6. This process involves understanding the basic components of polynomials and combining like terms for a simplified expression.
