The Deep Dive
To solve the inequality
, we first need to set a common ground by getting all terms on one side. We can rearrange it like this:
To combine the fractions, find a common denominator:
Now, simplifying the numerator:
So the full numerator becomes:
Now the inequality looks like this:
Next, we need to analyze when this entire rational expression is less than zero. The denominator will change signs based on the zeros:
-
leads to -
leads to
For the numerator,
does not have real roots (the discriminant
is negative), and since the leading coefficient is positive, it is always positive.
We can now consider the sign of the expression in intervals determined by the points
and
.
Intervals to test:
Testing values in each interval:
- For
: Positive numerator, positive denominator, result is positive. - For
: Positive numerator, positive denominator, result is positive. - For
: Positive numerator, negative denominator, result is negative.
So we find that the expression is only negative in the interval
.
However, since we originally had an inequality
, the solution to the inequality
is:
Do not forget that at
and
, the original fractions become undefined or zero, so they are excluded from the solution. Thus the final answer is:
