SUMMARY

The discussion focuses on solving the inequality \(\frac{3}{|x+1|-1}+\frac{2}{x}<1\) by analyzing two cases based on the value of \(x\). In the first case, where \(x \geq 0\), the solution simplifies to \(x > 5\). In the second case, where \(x < 0\), the inequality reduces to \(x^2 + 3x - 4 > 0\), leading to the solution set \(x < -4\) or \(x > 1\). The final conclusion confirms that the solution for the entire inequality is \(x > 5\) or \(x < -4\).

Problem:
[tex]\frac{3}{|x+1|-1}[/tex]+[tex]\frac{2}{x}[/tex]<1

My Solution:
There are 2 cases:
1) x[tex]\geq0[/tex],[tex]\frac{3}{x+1-1}[/tex]+[tex]\frac{2}{x}[/tex]<1
[tex]\frac{3}{x}[/tex]+[tex]\frac{2}{x}[/tex]<1
And you end up with... x>5.

2) x<0, [tex]\frac{3}{-x-1-1}[/tex]+[tex]\frac{2}{x}[/tex]<1
[tex]\frac{3x-2x-4}{-x^{2}-2x}[/tex]<1
... a few reductions later...
[tex]x^{2}[/tex]+3x-4>0
And the solution set for this case is, -4>x>1

My Question:
Is there something I'm missing or something else I need to do?

"-4 > x> 1" implies -4> 1! x2+ 3x- 4= (x+ 4)(x- 1)> 0 if and only if the two factors are of the same sign. x+4> 0, x- 1> 0 give x> -4 and x> 1 which are both satisfied for x> 1. x+4< 0, x-1< 0 give x< -4, x< 1 which are both satisfied for x< -4.
x2+ 3x- 4> 0 for x< -4 OR x> 1.
