Rationals and Radicals

Description

Addition of rational expressions involves combining rational expressions to create a new rational expression, often requiring a common denominator. Examples include 1 / x + 1 / 2x = 3 / 2x and 1 / (x + 1) + 1 / (x - 1) = 2x / (x2 - 1). This term introduces the concept of combining rational expressions, which is fundamental to operations involving fractions with polynomial expressions.

An oblique asymptote occurs when, for large values of x, the y-values of the graph approach but do not touch the graph of a linear function. An example is given where y = (x3 - 2x2 + 1) / (x2 - 2x - 3) approaches y = x as x approaches infinity. This term provides insight into the behavior of rational functions, essential for graphing and understanding limits in radical and rational contexts.
