1. Problem Description
The problem asks us to solve the inequality .
2. Solution Steps
We can rewrite the inequality as:
This can be split into two inequalities:
and
Let's solve the first inequality: .
Subtract 4 from both sides: .
Combine the terms on the left: .
Simplify the numerator: , which gives .
Multiply both sides by and reverse the inequality sign: .
Now we analyze the sign of the expression. The critical points are and .
We consider three intervals:
- : Both and are negative, so the fraction is positive.
- : is positive and is negative, so the fraction is negative.
- : Both and are positive, so the fraction is positive.
Therefore, the solution to the first inequality is or .
Now let's solve the second inequality: .
Add 4 to both sides: .
Combine the terms on the left: .
Simplify the numerator: , which gives .
Simplify: , so .
The critical points are and .
We consider three intervals:
- : Both and are negative, so the fraction is positive.
- : is negative and is positive, so the fraction is negative.
- : Both and are positive, so the fraction is positive.
Therefore, the solution to the second inequality is or .
Now we need to find the intersection of the two solutions.
The first solution is or , and the second solution is or .
Since , the intersection is or .
In interval notation, this is .
