Maybe we could get a common denominator:
And we could do those multiplications in the numerator:
And we could add the two fractions:
The numerator is always positive.
We can see that has no real roots because the discriminant is negative:
is positive for x=0 (it's 5), and everywhere else.
For to be negative, the denominator has to be negative.
Each factor has a zero (x=1 and x=2), is negative for lesser x values and positive for greater values.
The product will be negative for x such that .
For x=1 and x=2, the denominator is zero and the functions do not exist.
For x<1 and x>2 the function is positive.
So the solution is
