your solution will be all the x's when the graph is above the x-axis

I can see it there is a zero at x = 3

and there are 2 vertical asymptotes at

x = 2 , and x = -2

How about thinking about this intuitively

the numerator is always ≥ 0, since we squared something

Also we can see that x^2 - 4 is negative for values of x between -2 and 2, and x cannot be +2 or -2

so it looks like the expression is above the x-axis for x > 2 OR x < -2
