what are the challenges of working with rational expressions i've searched in my math book and online i can't seem to find that answer. Can somoene help me out ..
Since this is not my area of expertise, I searched Google under the key words "math rational expressions" to get these possible sources:

I hope this helps. Thanks for asking.
Working with rational expressions can be challenging due to a few reasons:
1. Simplification: One of the main challenges is simplifying rational expressions. This involves factoring numerators and denominators, canceling common factors, and reducing the expression to its simplest form. It requires a good understanding of factoring techniques and algebraic manipulations.
2. Adding and subtracting: Adding or subtracting rational expressions involves finding a common denominator, performing the necessary operations, and simplifying the result. This can be complex when the expressions have different denominators or involve variables.
3. Multiplying and dividing: Multiplying and dividing rational expressions require multiplying numerators together and denominators together, and then simplifying the result. Dividing involves multiplying by the reciprocal of the second expression. These operations can be cumbersome, especially when dealing with large or complicated expressions.
4. Solving equations: Solving equations involving rational expressions can be challenging as well. It often requires simplifying the expressions, finding common denominators, and isolating the variable. Sometimes, extraneous solutions may be introduced, adding to the complexity.
To overcome these challenges, it is crucial to have a strong foundation in algebra and practice regularly. It is recommended to familiarize yourself with factoring techniques, understand the rules of operations for rational expressions, and work through various examples and exercises to gain proficiency. Additionally, seeking additional resources such as textbooks, online tutorials, or working with a math tutor can be beneficial.
