Question 7071: I have been working on this problem forever and can not come up with the answer in the back of my book.
Please help me solve the following equation :
│x^2 + 5│ + │x - 2│ ≤ 8
This is what I did .
│x^2 + 5 + x - 2│≤ 8
-8 ≤ x^2 + 5 + x – 2 ≤ 8
-8 ≤ x^2 + x + 3 ≤ 8
then subtract -3 from all sides and get this
-11 ≤ x^2 + x ≤ 5, Then completing square for middle getting this
-11 + 1/4 ≤ x^2 + x + 1/4 ≤ 5 + 1/4
-43/4 ≤ x^2 + x + 1/4 ≤ 21/4
-43/4 ≤ (x + 1/2)^2 ≤ 21/4
Then don’t go any further because I now that I can not get the answer that is in the book.
Please tell me where I am going wrong.
TIA,
del

Question 8516: I need to solve the absolute value equation.
5+3|x-4|=0
This is what I tried, but I'm not sure if I'm correct. I believe the equation is unsolvable.
5+3|x-4|=0
-5 -5
-------------
3|x-4|=-5
3 3
----------
|x-4|=-5/3--unsolvable ?

Question 8588: Are there always two answers when solving for an absolute value? Do you have to put the positive and negative or no? Here is my problem and here is my answer:
7-4(3-6)2 (that 2 is squared not a regular 2)
---------
|3 -12|
so I got
3(-3)squared 3(9) 27
----- ---- -- = 3
| -9 | 9 9
So is that answer right or is it {3, -3}?
