Question 1001185
Solve the rational inequality. Express your answer using interval notation. 
(2x)/(x^2 + 16) ≤ 0 
I think that I need to factor the bottom and make it: (2x)/(x+4)(x-4) but I'm not sure where to go from there. Please show work. Thank you! 
----
Note: Solve for the equality::
2x = 0
x = 0
That is part of the solution.
-----------
Note: Solve the inequality::
2x and (x^2+16) MUST have opposite signs.
But x^2+16 is never negative.
So 2x MUST be negative
2x < 0 when x < 0
That is also part of the solution.
-----
Ans: x <= 0
