Determine the value(s) for which each expression is undefined.

(-n2 + 36)
---------------------------
(n - 6) (n2 + 12n + 36)

Don't know any way to get subscripts with this limited editor. An exponent of 2 is alt-253, an exponent of 3 is alt-0179, and the rest of the time you're stuck with ^. π is alt-227, √ is alt-251. And so on. Check your character editor.



(-n² + 36)



n² = 36

n= √36

n= 6



---------------------------

(n + -6) (n² + 12n + 36)

factor: (n+ -6)(n + 6)(n + 6)

n= 6 or -6

The top of the equation is irrelevant, its the bottom that counts.



The bottom factors to: (n-6)(n+6)(n+6)



So, any number 'n' that would result in a zero value would make the expression invalid, since division by zero is, by definition, invalid.



Therefore the expression is invalid if n=6 or -6.
um...

the denominator has 2 be 0



factor:



(n+6)(n+6) n-6 is prime.

since its multiplication, 1 has 2 be 0.



so n is 6- or 6 to be undefined

You need to figure out what n is then you can solve the problem

In (-n2+36)you need to figure out what n is,then multiply nX2.Once you're done with that,add 36.then you've got your answer.

n=6,

n=-6



in both cases whats below the ---------- is zero and thus is the expression not defined.
