Answer:
It's the last choice: (x + 5) / (x^2 - 7x + 10).
Step-by-step explanation:
x^2 - 7x + 10
= (x - 5)(x - 2)
If these are a denominator of a rational expression then 2 and 5 will be excluded values.
This is because x = 5 or x = 2 makes the denominator = zero and the function then becomes undefined.
So the answer is (x + 5) / (x^2 - 7x + 10).
