rational expressions
In this page we are going to discuss about rational expressions concept . Expression is a finite combination
of symbols that are well formed and rational expressions is that where the numerator and the denominator or
both of them are polynomials. A rational number is a few number that can be printed in the form p/q, there are
p is specified the integer and q is also specified the integers and q ? 0.
Rational expression:
If p(x) and q(x) are two polynomials, q(x) [!=] 0, then the quotient [(p(x))/(q(x))] is called a rational expression.
* p(x) is known as numerator and q(x) is known as the denominator of the rational expression
* [(p(x))/(q(x)) ] need not be a polynomial
Since a rational number is of the form p/q, we can say that a rational expression is also of the form p/q, but
since it is an expression, it contains variables along with numbers .

Steps to reduce a given rational expression to its lowest terms:
* Factorize each of the two polynomials p(x) and q(x)
* Find highest common divisor of p(x) and q(x)
* If h.c.f. = 1 , then the given rational expression [(p(x))/(q(x))] is in its
lowest terms
* If h.c.f [!=] 1, then divide the numerator p(x) and denominator q(x) by
the h.c.f of p(x) and q(x)
* The rational expression obtained in Step III or Step IV is in its lowest
terms
