7.5: Solving Rational Equations
Begin solving rational equations by multiplying both sides by the LCD. The resulting equivalent equation can be solved using the techniques learned up to this point. Multiplying both sides of a rational equation by a variable expression introduces the possibility of extraneous solutions. Therefore, we must check the solutions against the set of ...

Solving Rational Equations
Solving Rational Equations. A rational equation is a type of equation where it involves at least one rational expression, a fancy name for a fraction. The best approach to address this type of equation is to eliminate all the denominators using the idea of LCD (least common denominator).
7.4 Solve Rational Equations
Solve Rational Equations. We have already solved linear equations that contained fractions. We found the LCD of all the fractions in the equation and then multiplied both sides of the equation by the LCD to "clear" the fractions. We will use the same strategy to solve rational equations. We will multiply both sides of the equation by the LCD.
Rational Function
A rational function is a function that is the ratio of polynomials. Any function of one variable, x, is called a rational function if, it can be represented as f(x) = p(x)/q(x), where p(x) and q(x) are polynomials such that q(x) ≠ 0.For example, f(x) = (x 2 + x - 2) / (2x 2 - 2x - 3) is a rational function and here, 2x 2 - 2x - 3 ≠ 0.. We know that every constant is a polynomial and hence ...

A nice application of rational functions involves the amount of work a person (or team of persons) can do in a certain amount of time. We can handle these applications involving work in a manner similar to the method we used to solve distance, speed, and time problems. Here is the guiding principle. Note.
