Simplifying the Expression: (-t³ + 5t² - 6t) + (8t² - 8t)
This expression involves combining like terms, which are terms with the same variable and exponent. Here's how we can simplify it:
1. Identify Like Terms:
- -t³: This term has no other like terms in the expression.
- 5t² and 8t²: Both have the variable 't' raised to the power of 2.
- -6t and -8t: Both have the variable 't' raised to the power of 1.
2. Combine Like Terms:
- -t³: Remains the same.
- 5t² + 8t² = 13t²
- -6t - 8t = -14t
3. Final Simplified Expression:
The simplified expression is -t³ + 13t² - 14t.
Summary
By identifying and combining like terms, we were able to simplify the expression from a long series of terms to a more concise form. This process is crucial for solving equations, simplifying algebraic expressions, and performing other mathematical operations.
