Please ellaborate to the following...

Please ellaborate to the following discussion..."What are rational expressions?

Rational expressions are the ratios of two polynomials. also they are polynomial fractions and anything you could do with regular fractions can be done with rational expressions. The expressions also have variables such as x. When you work with rational expressions they need to be evaluated, also know the values that cause division by zero. Basically you would find the domain of the rational expressions.

Why must me always be mindful of the final value of the denominator in a rational expression?

We must be mindful of the final value of the denominator because the expression would be undefined whenever the denominator equals 0. Meaning that it would not be able to be solved by zero. The domain is considered that all values under x is allowed. Then you would find the value or values of x that would include using division by zero."

Thank you for your help!!
