Answer 1

The option that is not a rational expression is $\frac{3x + 4\sqrt{x} -7}{2x+2}$

How to find rational expression?

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:

$\frac{x^{2}+9 }{x + 1}$

Therefore, the option that is not a rational expression is as follows;

$\frac{3x + 4\sqrt{x} -7}{2x+2}$

Answer 2

The expression that is not a rational expression is:

$\frac{(x + 3)(2x - 1)}{x + 3}$

What is a rational expression?

A rational expression is an expression that has a variable in the denominator.

For expression $\frac{(x + 3)(2x - 1)}{x + 3}$, x + 3 is a common term to the numerator and denominator, hence it is simplified to 2x - 1 and is not a rational expression.
