In order for a fraction to be undefined, the denominator or number on the bottom must be equal to zero. So we set the bottom binomial equal to zero.

x + 10 = 0
x = 0 - 10
x = - 10

Option D is your answer.

The quotient will be undefined when the denominator is zero, since division by zero is undefined. The denominator is x+10. We can find the answer by setting this equal to zero and solving for x:

[tex]x+10=0[/tex]
[tex]x+10-10=0-10[/tex]
[tex]x=-10[/tex]

The answer is D.
