Understanding the (a+b+c)(a+b-c) Formula
The formula (a+b+c)(a+b-c) is a useful algebraic expression that can be simplified to a more compact form. This formula is often used in various mathematical problems, particularly in algebra and geometry.
Expanding the Formula
The formula can be expanded using the distributive property of multiplication. Let's break down the steps:
-
Multiply the first term of the first expression with each term of the second expression:
- a(a+b-c) = a² + ab - ac
-
Multiply the second term of the first expression with each term of the second expression:
- b(a+b-c) = ab + b² - bc
-
Multiply the third term of the first expression with each term of the second expression:
- c(a+b-c) = ac + bc - c²
-
Add all the resulting terms together:
- a² + ab - ac + ab + b² - bc + ac + bc - c²
-
Combine like terms:
- a² + 2ab + b² - c²
The Simplified Formula
Therefore, the simplified form of the formula (a+b+c)(a+b-c) is a² + 2ab + b² - c².
