Answer
Doesn't make sense.
Work Step by Step
To add fractions or rational expressions with the same denominator,
add numerators and place the sum over the common denominator.
$\displaystyle \frac{3x+1}{4}+\frac{x+2}{4}=\frac{3x+1+x+2}{4}=\frac{4x+3}{4}$
The numerator can't be factored, so no common factors exist.\\\\
It doesn't make sense to divide both the numerator and denominator when no common factor exists.
