Any number that can be expressed as a fraction is a rational number otherwise it is an irrational number.
One possible expression is [ 1/(x - 4)+ 1/x ].
The answer is given below.
The expression X/(X+8) is undefined at X=-8, because that would be division by zero.

If the algebraic expression can be written in the form of a(x)/b(x) where a(x) and b(x) are polynomial functions of x and b(x) ≠0, then the expression is a rational algebraic expression.

I can see no rational expression below.
Multiplying Rational Expressions After studying this lesson, you will be able to: * Multiply rational expressions. Steps to multiply a rational expression: 1. Cancel numerator to denominator if possible (don't cancel parts of a binomial or trinomial) 2. Factor the numerators and denominators if possible. 3. Multiply straight across - remember, you don't need a common denominator to multiply fractions (or rational expressions). Example 1 Nothing will cancel. Nothing will factor. All we have to do is multiply. This is the simplified answer. Example 2 We can do some canceling and reducing in this problem. 2 and 16 reduces; 9 and 3 reduces, reduce the variables. Now, we multiply. This is the simplified expression. Example 3 We can reduce 12 and 3 and reduce the variables Now, factor the second denominator. Cancel the identical binomials (x + 5 ) This is the simplified expression. Example 4 Factor Cancel the identical binomials. This is the simplified expression. Example 5Factor Cancel the identical binomials. This is the simplified expression. THIS WAS MADE BY: www.algebra-online.com/multiplying-rational-expressions-1.htm Hope this helped !
