What are the Classifications of Algebraic Equations?

Published in Algebra 2 mins read

Algebraic equations can be classified in several ways, based on different characteristics such as the number of terms, the degree of the equation, and the type of functions involved. Here, we will focus on classification based on the number of terms:

Classification Based on Number of Terms

Algebraic expressions, which form the basis of algebraic equations, can be classified based on the number of terms they contain:

  • Monomial: An algebraic expression with only one term. Example: 5x, 7, -3y^2.

  • Binomial: An algebraic expression with two terms. Example: x + 3, 2y - 5x, a^2 - b^2.

  • Polynomial: An algebraic expression with one or more terms, where the exponents are non-negative integers. Monomials and binomials are also considered polynomials. Example: x^2 + 2x + 1, 4a^3 - 2a + 7, 5x. Note that terms can be added or subtracted. Generally, if the expression has more than two terms, it is called a polynomial.

Further Classification Considerations

While the number of terms is a simple way to classify algebraic expressions, it's important to note other classification methods exist based on:

  • Degree: Equations can be classified by their highest degree (the highest power of the variable). For example, a linear equation has a degree of 1, a quadratic equation has a degree of 2, and so on.

  • Type of Function: Equations can also be categorized by the types of functions they involve, such as polynomial equations, exponential equations, logarithmic equations, trigonometric equations, and so on.

In conclusion, algebraic equations are classified based on number of terms as monomials (one term), binomials (two terms), and polynomials (one or more terms with non-negative integral exponents).
