Another rational expression.
Yes.
Any number that can be expressed as a fraction is a rational number otherwise it is an irrational number.
The expression written in the question is the rational expression.
To determine the domain of an expression or equation in 8th grade, identify the values of the variable that make the expression valid. For example, in rational expressions, exclude values that make the denominator zero, and for square roots, ensure the expression inside the root is non-negative. Solve any inequalities or equations that arise from these conditions to find the domain. Finally, express the domain in interval notation or as a set of values.
A rational algebraic expression is the ratio of two algebraic expressions. That is, one algebraic expression divided by another. It is important that the domain is defined in such a way the the rational expression does not involve division by 0.
Another rational expression.
Yes.
If you divide a rational expression by another rational expression, you will again get a rational expression.
Rational expressions are fractions and are therefore undefined if the denominator is zero; the domain of a rational function is all real numbers except those that make the denominator of the related rational expression equal to 0. If a denominator contains variables, set it equal to zero and solve.

I can see no rational expression below.
The expression is not factorable with rational numbers.
another rational expression.
The domain of a rational function is the whole of the real numbers except those points where the denominator of the rational function, simplified if possible, is zero.
A rational expression is not defined whenever the denominator of the expression equals zero. These will be the roots or zeros of the denominator.
