Expanding the Expression (5n−5)(2+2n)

This article explores the expansion of the expression (5n−5)(2+2n). We will achieve this through the use of the distributive property.

The Distributive Property

The distributive property states that for any numbers a, b, and c, the following equation holds true:

a(b + c) = ab + ac

This property allows us to multiply a sum by a single term by distributing the multiplication over each term in the sum.

Expanding the Expression

Let's apply the distributive property to our expression:

  1. Distribute the 5n: (5n−5)(2+2n) = 5n(2+2n) - 5(2+2n)

  2. Distribute the -5: 5n(2+2n) - 5(2+2n) = 10n + 10n² - 10 - 10n

  3. Combine like terms: 10n + 10n² - 10 - 10n = 10n² - 10

Conclusion

Therefore, the expanded form of the expression (5n−5)(2+2n) is 10n² - 10. This process showcases the power of the distributive property in simplifying expressions and making them easier to work with.
