Introduction

In algebra, forming expressions is a fundamental concept that helps us represent mathematical relationships between variables. When we are given a problem that involves multiplying a number by itself and adding it to thrice the value of another variable, we need to form an algebraic expression that represents this relationship. In this article, we will explore how to form the algebraic expression when a number OC is multiplied by itself and added to thrice the value of y.

Understanding the Problem

To form the algebraic expression, we need to understand the given problem. We are told that a number OC is multiplied by itself, which means we need to square the number OC. This can be represented as (OC)^2. Additionally, we are told that the result of this multiplication is added to thrice the value of y. This means we need to multiply y by 3 and add it to the result of the multiplication of OC by itself.

Forming the Algebraic Expression

To form the algebraic expression, we need to combine the two parts of the problem. The first part involves squaring the number OC, which can be represented as (OC)^2. The second part involves multiplying y by 3, which can be represented as 3y. To add these two parts together, we use the addition operator (+). Therefore, the algebraic expression can be formed as:

(OC)^2 + 3y

Simplifying the Algebraic Expression

The algebraic expression (OC)^2 + 3y is already in its simplest form. However, we can simplify it further by using the order of operations (PEMDAS). According to PEMDAS, we need to evaluate the exponentiation first, followed by the addition. Therefore, the simplified algebraic expression remains the same:

(OC)^2 + 3y

Example

Let's consider an example to illustrate how to form the algebraic expression. Suppose we are given the problem: "Form the algebraic expression when 2x is multiplied by itself and added to thrice the value of y." To form the algebraic expression, we need to square 2x, which can be represented as (2x)^2. We also need to multiply y by 3, which can be represented as 3y. Therefore, the algebraic expression can be formed as:

(2x)^2 + 3y

Expanding the Algebraic Expression

To expand the algebraic expression (2x)^2 + 3y, we need to evaluate the exponentiation first. According to the exponentiation rule, (2x)^2 can be expanded as 4x^2. Therefore, the expanded algebraic expression becomes:

4x^2 + 3y

Conclusion

In this article, we have explored how to form the algebraic expression when a number OC is multiplied by itself and added to thrice the value of y. We have seen that the algebraic expression can be formed as (OC)^2 + 3y. We have also simplified the algebraic expression using the order of operations (PEMDAS) and expanded it using the exponentiation rule. By following these steps, we can form the algebraic expression for any given problem.
