The option that is not a rational expression is ![\frac{3x + 4\sqrt{x} -7}{2x+2}](https://tex.z-dn.net/?f=%5Cfrac%7B3x%20%2B%204%5Csqrt%7Bx%7D%20-7%7D%7B2x%2B2%7D)
<h3>How to find rational expression?</h3>
Rational expression are fraction whose numerator and denominator are polynomials.
In other words, rational expression is the ratio of two polynomials.
Therefore, an example of a ration expression is as follows:
![\frac{x^{2}+9 }{x + 1}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B2%7D%2B9%20%7D%7Bx%20%2B%201%7D)
Therefore, the option that is not a rational expression is as follows;
![\frac{3x + 4\sqrt{x} -7}{2x+2}](https://tex.z-dn.net/?f=%5Cfrac%7B3x%20%2B%204%5Csqrt%7Bx%7D%20-7%7D%7B2x%2B2%7D)
