Answer:
A rational algebraic expression (or rational expression) is an algebraic expression that can be written as a quotient of polynomials, such as x2 + 4x + 4. An irrational algebraic expression is one that is not rational, such as √x + 4.
Step-by-step explanation:
What are the rules in rational algebraic expressions?
An algebraic expression where both the numerator and the denominator are polynomials e.g. is called a rational expression. Since the denominator can't be zero there are values of x which are excluded from the rational expression. The expression above has an excluded value of zero.
