Polynomials are an essential part of algebra and mathematics in general. They are expressions that consist of variables and coefficients. Today, we’re going to explore the sum of polynomials and how to solve it.
Whether you’re a math enthusiast or a student looking for a refresher, this article is here to help you understand the concept better. So, let’s dive into the world of polynomials and explore the sum of different polynomial expressions.
The Basics of Polynomials
Before we dive into the sum of polynomials, let’s brush up on the basics. A polynomial is an expression consisting of variables, coefficients, and exponents. These expressions can have one or more terms, and the terms are usually separated by addition or subtraction.
In our case, we are dealing with the sum of two polynomial expressions – (7×3 – 4×2) + (2×3 – 4×2). To find the sum, we need to combine like terms and simplify the expression.
Combining Like Terms
When dealing with polynomials, it’s essential to combine like terms to simplify the expression. Like terms are terms that have the same variable raised to the same power. In our example, the like terms are 7×3, 2×3, -4×2, and -4×2. By combining these like terms, we can find the sum of the polynomials.
Combining like terms involves adding or subtracting the coefficients while keeping the variable and exponent the same. Let’s move on to the next subheading to see how this process is applied to our specific example.
Summing the Polynomials
Now that we understand the basics and have identified the like terms, it’s time to find the sum of the polynomials. In our example, we have (7×3 – 4×2) + (2×3 – 4×2). By combining the like terms, we can simplify this expression and find the sum of the polynomials.
To sum the polynomials, we add or subtract the coefficients of the like terms while keeping the variables and exponents unchanged. This process allows us to simplify the expression and find the sum of the given polynomials. Let’s move on to the next subheading to see the step-by-step process of finding the sum.
Step-By-Step Process
When dealing with the sum of polynomials, it’s helpful to follow a step-by-step process to ensure accuracy and efficiency. By following a systematic approach, we can simplify the expression and find the sum with ease. Let’s break down the process into simple steps to better understand how to find the sum of polynomials.
In the next few paragraphs, we’ll go over a step-by-step process of finding the sum of the given polynomials, ensuring that you have a clear understanding of the concept and how to apply it in practice.
