Simplifying the Expression (a-1)(2a+2)

This article will guide you through simplifying the expression (a-1)(2a+2) using the distributive property.

Understanding the Distributive Property

The distributive property states that for any numbers a, b, and c:

a(b + c) = ab + ac

This means we can multiply a term by a sum by multiplying the term by each term within the sum individually.

Applying the Distributive Property to (a-1)(2a+2)

To simplify (a-1)(2a+2), we'll apply the distributive property twice:

  1. Distribute (a-1) over (2a+2): (a-1)(2a+2) = a(2a+2) - 1(2a+2)

  2. Distribute a and -1: a(2a+2) - 1(2a+2) = 2a² + 2a - 2a - 2

  3. Combine like terms: 2a² + 2a - 2a - 2 = 2a² - 2

Conclusion

Therefore, the simplified form of (a-1)(2a+2) is 2a² - 2.
