The excluded values of a rational expression are 2 and 5. Which of the following could be this expression?

x2 - 7x+10

X+5

x2 + 7x + 10

X+5

X+5

x2 + 7x+10

X+5

x2 - 7x+10

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).

Answer: The answer should be B.

Step-by-step explanation:

The trinomial equation should go on top

5 x 2 = 10, & 5 + 2 = 7
