Rational expressions are commonly used in engineering to model and analyze relationships between variables, particularly in fields such as fluid dynamics, control systems, and circuit design. They help engineers represent ratios of quantities, such as voltage, current, and resistance in electrical circuits, allowing for simplified calculations and system optimization. Additionally, rational expressions facilitate the assessment of performance metrics and design parameters, aiding in the development of efficient engineering solutions.

Why is it important to study rational expression?
Studying rational expressions is crucial because they are fundamental in algebra and are used to model and solve real-world problems involving ratios and rates. Understanding how to manipulate and simplify these expressions enhances critical thinking and problem-solving skills. Additionally, rational expressions form the basis for more advanced topics in mathematics, including calculus and functions, making them essential for further studies in science, engineering, and economics.
