So this is how to know if a rational expression is proper or improper: proper: the degree of the top is less than the degree of the bottom. proper: 1 x 1. deg (top) < deg (bottom) another example: x x3 − 1. improper: the degree of the top is greater than, or equal to, the degree of the bottom. improper:. T 1 = t 1 t2 − t − 2 = (t − 2)(t 1) lcm: (t 1)(t − 1) compare each original denominator and the new common denominator. now rewrite the rational expressions to each have the common denominator of (t 1)(t– 2). you need to multiply t– 2 to get the lcd, so multiply the entire rational expression by t − 2 t − 2.

Exercise 7.1.4 rational expressions. an object’s weight depends on its height above the surface of earth. if an object weighs 120 pounds on the surface of earth, then its weight in pounds, w, x miles above the surface is approximated by the formula. w = 120 ⋅ 40002 (4000 x)2. To simplify a rational expression, follow these steps: determine the domain. the excluded values are those values for the variable that result in the expression having a denominator of 0. factor the numerator and denominator. find common factors for the numerator and denominator and simplify.
