Simplifying the Expression: (-w3 + 8w2 - 3w) + (-8w2 + w + 3)

This article will guide you through the steps of simplifying the given expression: (-w3 + 8w2 - 3w) + (-8w2 + w + 3).

Understanding the Expression

The expression consists of two sets of terms enclosed in parentheses. Let's break down each set:

  • (-w3 + 8w2 - 3w): This set includes terms with different powers of 'w'.
    • -w3: This represents the term with the highest power of 'w' (3).
    • 8w2: This represents the term with the power of 'w' as 2.
    • -3w: This represents the term with 'w' raised to the power 1.
  • (-8w2 + w + 3): This set also includes terms with different powers of 'w', along with a constant term.
    • -8w2: This represents the term with 'w' raised to the power 2.
    • w: This represents the term with 'w' raised to the power 1.
    • 3: This is a constant term.

Simplifying the Expression

To simplify the expression, we need to combine like terms. Like terms are those that have the same variable raised to the same power.

  1. Remove parentheses: Since we are adding the two sets of terms, we can remove the parentheses without changing the signs of the terms:

    -w3 + 8w2 - 3w - 8w2 + w + 3

  2. Combine like terms:

    • w3 terms: There is only one term with w3: -w3
    • w2 terms: We have 8w2 and -8w2, which combine to give 0
    • w terms: We have -3w and w, which combine to give -2w
    • Constant terms: We have only one constant term: 3
  3. Write the simplified expression:

    -w3 + 0 - 2w + 3

    Therefore, the simplified form of the expression is -w3 - 2w + 3.

Conclusion

By combining like terms, we have successfully simplified the expression (-w3 + 8w2 - 3w) + (-8w2 + w + 3) to -w3 - 2w + 3. This process demonstrates how to handle expressions with multiple terms and different powers of variables.
