Consider the following expressions: 1. x + x ^2- 1 x 2. a x^2+b x+x-c+ d c - e x^2 3. 3 x^2-5 x+a b 4. 2 x ^2- ax + b ^3 5. 1 x - 2 x+5 Which of the above are rational expressions?

Step-by-step solution

A rational expression is nothing more than a fraction in which the numerator and denominator are polynomials. Here are some example of rational expressions are (x+x^2+ 1 x ), (3 x^2-5 x+a b ) , 2 x^2-a x+a b
