Question 40619
Solve each rational inequality and state the solution set using interval notation.
{{{(a) / (a+2) > 0}}}
First we need to eliminate the fraction {{{(a) / (a+2)}}} by multiplying both sides of the equation by the denominator (a + 2).
{{{(a+2)* ((a) / (a+2)) > 0(a+2)}}} 
The a + 2 cancels out on one side and the 0(a+2) = 0, so now we have...
{{{a > 0}}}
This tells us that (a) is equal to all real numbers greater than zero.
So our solution set in interval notation is...
(0,~) or (0, infinity)
I hope this helps.
Good Luck!
