-12√[2x - 3]  >    -36         

 

Divide both sides  by -12   and reverse the inequality sign

 

√[2x - 3 ]  <   3            square both sides

 

2x - 3   <  9        add 3 to both sides

 

2x <   12            divide both sides by 2

 

x < 6   

 

However.....also remember  that      2x - 3 must be  ≥   0

 

So the other solution is

 

2x - 3 ≥  0

2x ≥ 3

x ≥ 3/2

 

So.....the solution  is

 

3/2   ≤  x  <  6

 

The last choice is correct
