Expanding the Expression (a+b)(c+d+e)
This article explores the expansion of the expression (a+b)(c+d+e). This is a common algebraic operation that demonstrates the distributive property and is fundamental in various mathematical applications.
Understanding the Distributive Property
The distributive property states that multiplying a sum by a number is the same as multiplying each term of the sum by the number separately and then adding the results. In mathematical terms:
a(b + c) = ab + ac
This property is crucial for expanding expressions like (a+b)(c+d+e).
Expanding the Expression
To expand (a+b)(c+d+e), we can apply the distributive property twice:

Distribute (a+b) over (c+d+e): (a+b)(c+d+e) = a(c+d+e) + b(c+d+e)

Distribute 'a' and 'b' over the terms inside the parentheses: a(c+d+e) + b(c+d+e) = ac + ad + ae + bc + bd + be
Therefore, the expanded form of (a+b)(c+d+e) is ac + ad + ae + bc + bd + be.
Applications of Expanding Expressions
Expanding expressions like (a+b)(c+d+e) has various applications in mathematics, including:
 Simplifying equations: Expanding can help simplify complex equations and make them easier to solve.
