Answer: OPTION B.

Explanation:

Given the rational expressions
(3x+2)/(x-1) and
(2x-5)/(x-1), we can observe that both have the same denominator, then we can add them.

We must rewrite the denominator
x-1 and add the numerators. Then:


=((3x+2)+(2x-5))/(x-1)

Therefore, adding the like terms on the numerator, we get the following sum:


=(5x-3)/(x-1)

We can observe that this sum matches with the sum shown in the option B.

For this case we have that the fractions have the same denominator, then we can rewrite as:


\frac {3x + 2 + (2x -5)} {x-1} =

We eliminate the parenthesis:


+*+=+


+*-=-


\frac {3x + 2 + 2x - 5} {x-1} =

We add common terms of the numerator:


\frac {5x-3} {x-1}

Thus, the correct expression is option B.

Answer:

Option B
