Answer
$\text{True}$
Work Step by Step
A rational expression $\dfrac{A}{B}$ is said to be proper if the degree of the polynomial in numerator is less than the degree of the polynomial in its denominator.
Here, the degree of the polynomial in the numerator is $1$ while the degree of the polynomial in the denominator is $2$.
Since $1<2$, then the given rational expression is proper.
Hence, the given statement is true.
