Question 586388: find the domain of 6x over x^2-25

The domain defines all values of x that makes sense for the expression.
In this case, you just don't want the denominator to go to zero.
So, set the denominator to zero and solve for x. These are the values that x cannot take:
x^2-25 = 0
x^2 = 25
x = +- 5
.
Domain:
(-oo, -5) U (-5, 5) U (5, +oo)
where
oo is for infinity
.
