Which methods can be used to expand (x+3)3?

Solution

Here use the Distributive Property of Multiplication Across the Addition.

The Distributive Property is a.(b + c) = a. b + a.c

Using the distributive property, we can expand the given expression.

(x + 3).3 = 3.x + 3.3

That is the expanded form.
