TutorVista helps in Rational expressions

This article is based on rational expressions and how to simplify expressions. Before proceeding further, let’s talk about Rational numbers. In a simple mathematical way we can say that any number that can be expressed as fraction is known as Rational number. For example 2/3 is a rational number, here 2 is the numerator and 3 is a denominator. An essential condition for rational number is that denominator can never be a zero. Decimal number is also a rational number, 1.5 is a rational number that can be expressed as fraction, 1.5 can be written as 15/10 or 3/2.
Expression is a finite combination of symbols that are well formed. A rational expression is nothing more than a fraction in which the numerator and/or the denominator are polynomials. Here are some examples of rational expressions to understand it better.
It is an equation where 6 is a numerator and x-1 is a denominator. Simplify rational expression means converting complexity into simple and then solving it. In other words, breaking a problem, into simple terms or terminologies can be defined as simplification of rational expressions.Simplify expressions comes with rationalization techniques where we rationalize the denominator. Rationalizing a denominator is the process by which a fraction containing radicals in the denominator is rewritten to have only rational numbers in the denominator.
Sometimes rational expressions come with various algebraic expressions or decimal numbers and with fractions that makes it quite difficult to solve such type of expressions.
