Question 640468
<font face="Times New Roman" size="+2">


You need to set each of the three denominators equal to zero and solve the resulting equations.  Every root determined thereby is a value excluded from the domain.


So, yes, you must use the *[tex \LARGE x^2] because it is part of *[tex \LARGE x^2\ +\ x\ -\ 6]


Set *[tex \LARGE x^2\ +\ x\ -\ 6\ =\ 0].  Now solve the quadratic.  Hint: It factors.

*[tex \LARGE e^{i\pi}\ +\ 1\ =\ 0]
My calculator said it, I believe it, that settles it
