Simplifying the Expression: (-3m^4 - m^3) - (5m^2 + m^4)
This article will guide you through the process of simplifying the expression (-3m^4 - m^3) - (5m^2 + m^4).
Understanding the Process
The key to simplifying this expression is to combine like terms. Remember, like terms have the same variable and exponent. For example, -3m^4 and m^4 are like terms because they both have m raised to the power of 4.
Step-by-Step Simplification
-
Distribute the negative sign:
- When we have a minus sign before parentheses, we distribute it to each term inside the parentheses:
- (-3m^4 - m^3) - (5m^2 + m^4) becomes -3m^4 - m^3 - 5m^2 - m^4
-
Combine like terms:
- m^4 terms: -3m^4 - m^4 = -4m^4
- m^3 terms: -m^3 (there are no other m^3 terms)
- m^2 terms: -5m^2 (there are no other m^2 terms)
-
Write the simplified expression:
- Combining all the terms, the simplified expression is -4m^4 - m^3 - 5m^2.
Conclusion
Therefore, the simplified form of the expression (-3m^4 - m^3) - (5m^2 + m^4) is -4m^4 - m^3 - 5m^2. By following the steps of distributing the negative sign and combining like terms, we can simplify complex expressions into a more manageable form.
