Simplifying Algebraic Expressions: (1/4a - a^3 - 3) + (2a^3 - 1/2a^2 + 8)
In algebra, simplifying expressions means combining like terms to make the expression as concise as possible. Let's break down the steps to simplify the given expression:
(1/4a - a^3 - 3) + (2a^3 - 1/2a^2 + 8)
1. Identify Like Terms:
- a^3 terms: -a^3 and 2a^3
- a^2 terms: -1/2a^2
- a terms: 1/4a
- Constant terms: -3 and 8
2. Combine Like Terms:
- a^3 terms: -a^3 + 2a^3 = a^3
- a^2 terms: -1/2a^2
- a terms: 1/4a
- Constant terms: -3 + 8 = 5
3. Write the Simplified Expression:
a^3 - 1/2a^2 + 1/4a + 5
Therefore, the simplified form of the expression (1/4a - a^3 - 3) + (2a^3 - 1/2a^2 + 8) is a^3 - 1/2a^2 + 1/4a + 5.
