6. What is it
The expressions which are not polynomials are called
rational algebraic expressions so how do you describe an
algebraic expression?

7. Example 1.

8. Activity 2. AM I RATIONAL?

9. What I need to remember
 A rational algebraic expression is a fraction of
polynomials with the symbol
𝑃
𝑄
, where P as the numerator
and Q as the denominator are polynomials and Q must not
be equal to zero (0)
