In algebra, we often come across expressions that involve the addition or subtraction of two or more terms. One such expression is 9x square plus 4x square. In this article, we will delve into the world of algebra and explore the concept of 9x square plus 4x square, its properties, and how to simplify it.

What is 9x Square Plus 4x Square?

9x square plus 4x square is an algebraic expression that involves the addition of two terms: 9x square and 4x square. To understand this expression, let's break it down into its individual components.

9x square: This term represents the square of 9x, which is a product of 9 and x. In mathematical notation, it is represented as (9x)^2.
4x square: This term represents the square of 4x, which is a product of 4 and x. In mathematical notation, it is represented as (4x)^2.

When we add these two terms together, we get 9x square plus 4x square.

Properties of 9x Square Plus 4x Square

Before we simplify the expression, let's explore some of its properties.

Commutative Property: The commutative property states that the order of the terms does not change the result. In other words, 9x square plus 4x square is equal to 4x square plus 9x square.
Associative Property: The associative property states that the order in which we add the terms does not change the result. In other words, (9x square plus 4x square) plus 5x square is equal to 9x square plus (4x square plus 5x square).
Distributive Property: The distributive property states that we can distribute a single term to multiple terms. In other words, 9x square plus 4x square can be rewritten as (9+4)x square.

Simplifying 9x Square Plus 4x Square

Now that we have explored the properties of 9x square plus 4x square, let's simplify the expression.
