Introduction

Polynomials are algebraic expressions consisting of variables and coefficients combined using addition, subtraction, and multiplication. Simplifying polynomials is an essential skill in mathematics, as it helps to reduce complex expressions into their simplest form, making them easier to work with. In this article, we will explore the process of simplifying polynomials, using a specific example to illustrate the steps involved.

The Example Polynomial

The polynomial we will be simplifying is given by:

${ 10abc^2 + 23a^2bc - abc^2 - 15a^2bc + abc^2 - 2a^2bc }$

Step 1: Combine Like Terms

The first step in simplifying the polynomial is to combine like terms. Like terms are terms that have the same variable(s) raised to the same power. In this case, we can combine the terms with the same variable(s) raised to the same power.

${ 10abc^2 + 23a^2bc - abc^2 - 15a^2bc + abc^2 - 2a^2bc }$

We can start by combining the terms with the variable $a$ raised to the power of 2:

${ 23a^2bc - 15a^2bc - 2a^2bc }$

Next, we can combine the terms with the variable $a$ raised to the power of 1:

${ 10abc^2 - abc^2 + abc^2 }$

Finally, we can combine the terms with the variable $a$ raised to the power of 0 (i.e., the constant terms):

${ 0 }$

Step 2: Simplify the Expression

Now that we have combined like terms, we can simplify the expression further by combining the remaining terms.

${ 10abc^2 + 23a^2bc - abc^2 - 15a^2bc + abc^2 - 2a^2bc }$

We can start by combining the terms with the variable $a$ raised to the power of 2:

${ 23a^2bc - 15a^2bc - 2a^2bc }$

This simplifies to:

${ 6a^2bc }$

Next, we can combine the terms with the variable $a$ raised to the power of 1:

${ 10abc^2 - abc^2 + abc^2 }$

This simplifies to:

${ 10abc^2 }$

Finally, we can combine the terms with the variable $a$ raised to the power of 0 (i.e., the constant terms):

${ 0 }$

Step 3: Write the Simplified Expression

Now that we have simplified the expression, we can write the final answer.

${ 6a^2bc + 10abc^2 }$

Conclusion
