Introduction

In mathematics, polynomials are algebraic expressions consisting of variables and coefficients combined using only addition, subtraction, and multiplication. The standard form of a polynomial is a crucial concept in algebra, as it allows us to easily compare and manipulate polynomials. In this article, we will explore the standard form of a polynomial and provide a step-by-step guide on how to rewrite a given polynomial in its standard form.

What is the Standard Form of a Polynomial?

The standard form of a polynomial is a way of writing a polynomial with the terms arranged in descending order of their exponents. This means that the term with the highest exponent comes first, followed by the term with the next highest exponent, and so on. The standard form of a polynomial is also known as the "descending order" form.

Example: Standard Form of a Polynomial

Consider the polynomial: x4−2x5+x32+1\frac{x}{4} - 2x^5 + \frac{x^3}{2} + 1. To rewrite this polynomial in its standard form, we need to arrange the terms in descending order of their exponents.

Step 1: Identify the Terms


The given polynomial has four terms:

  1. x4\frac{x}{4}
  2. −2x5-2x^5
  3. x32\frac{x^3}{2}
  4. 11

Step 2: Arrange the Terms in Descending Order of Exponents


To arrange the terms in descending order of exponents, we need to compare the exponents of each term. The term with the highest exponent comes first, followed by the term with the next highest exponent, and so on.

Term Exponent
−2x5-2x^5 5
x32\frac{x^3}{2} 3
x4\frac{x}{4} 1
11 0

Step 3: Rewrite the Polynomial in Standard Form


Now that we have arranged the terms in descending order of exponents, we can rewrite the polynomial in its standard form.

x32−2x5+x4+1\frac{x^3}{2} - 2x^5 + \frac{x}{4} + 1

Answer

The polynomial x32−2x5+x4+1\frac{x^3}{2} - 2x^5 + \frac{x}{4} + 1 represents the standard form of the original polynomial.

Conclusion

In this article, we have explored the standard form of a polynomial and provided a step-by-step guide on how to rewrite a given polynomial in its standard form. We have also discussed the importance of arranging terms in descending order of exponents to ensure that the polynomial is in its standard form. By following these steps, you can easily rewrite any polynomial in its standard form and apply this concept to a wide range of mathematical problems.
