Introduction
Polynomials are a fundamental concept in algebra, and simplifying them is an essential skill for any math enthusiast. In this article, we will explore the process of simplifying polynomials, focusing on combining like terms and putting the given polynomial in standard form. We will examine two examples, and by the end of this article, you will be able to simplify polynomials like a pro.
What are Like Terms?
Like terms are terms that have the same variable(s) raised to the same power. In other words, they have the same base and exponent. For example, 2x^2 and 3x^2 are like terms because they both have the variable x raised to the power of 2.
Combining Like Terms
Combining like terms involves adding or subtracting the coefficients of like terms. The coefficients are the numbers that are multiplied by the variables. For example, in the expression 2x^2 + 3x^2, the like terms are 2x^2 and 3x^2. To combine them, we add the coefficients: 2 + 3 = 5. Therefore, the simplified expression is 5x^2.
Example 1: Simplifying a Polynomial
Let's consider the polynomial:
To simplify this polynomial, we need to combine like terms. We can start by grouping the terms that have the same variable(s) raised to the same power.
- The terms with x^3 y^3 are -5 x^3 y^3.
- The terms with x^4 y^2 are 8 x^4 y^2.
- The terms with x^2 y^4 are -2 x^2 y^4 and 3 x^2 y^4.
- The terms with x^8 are 8 x^8.
- The terms with x y^5 are -6 x y^5.
- The term with x y^8 is - x y^8.
Now, we can combine the like terms:
- The like terms with x^3 y^3 are -5 x^3 y^3.
- The like terms with x^4 y^2 are 8 x^4 y^2.
- The like terms with x^2 y^4 are -2 x^2 y^4 + 3 x^2 y^4 = x^2 y^4.
- The like terms with x^8 are 8 x^8.
- The like terms with x y^5 are -6 x y^5.
- The term with x y^8 is - x y^8.
The simplified polynomial is:
Example 2: Simplifying a Polynomial
Let's consider the polynomial:
To simplify this polynomial, we need to combine like terms. We can start by grouping the terms that have the same variable(s) raised to the same power.
- The terms with x y^5 are -7 x y^5 and 2 x y^5.
- The terms with x^2 y^4 are 5 x^2 y^4 and 3 x^2 y^4.
- The term with x^3 y^4 is -5 x^3 y^4.
Now, we can combine the like terms:
- The like terms with x y^5 are -7 x y^5 + 2 x y^5 = -5 x y^5.
- The like terms with x^2 y^4 are 5 x^2 y^4 + 3 x^2 y^4 = 8 x^2 y^4.
- The term with x^3 y^4 is -5 x^3 y^4.
The simplified polynomial is:
Putting the Polynomial in Standard Form
Once we have combined the like terms, we need to put the polynomial in standard form. The standard form of a polynomial is the form in which the terms are arranged in descending order of the exponent of the variable(s).
For example, the polynomial -5 x^3 y^3 + 8 x^4 y^2 + x^2 y^4 + 8 x^8 - x y^8 - 6 x y^5 is already in standard form.
However, the polynomial -5 x y^5 + 8 x^2 y^4 - 5 x^3 y^4 is not in standard form. To put it in standard form, we need to rearrange the terms in descending order of the exponent of the variable(s).
The standard form of the polynomial is:
