2. I have begun but got stuck midway.
3. I got an answer but I was told that it's wrong.
4. I got an answer and would like my work checked.
5. I have a question about someone else's work/solution.
6. I have completed the problem and don't need help anymore. Thank you.
7. None of the above

It's usually a good idea to get rid of radicals as soon as possible
member under root must be non-negative number
it will be
Can I show my answer as a guess point for owner?
Try alternative solutions for each radical elements. For example ( when first radical is non-negative and second is also non-negative… when first radical is negative and second is non-negative … etc)
You will get answers based on conditions.

As a helper, please do not give out answers that could be copied as a homework solution. Have the student work through the problem themselves and guide them along the way.
Give a try on it

and|a|^2=a
When |x^2 -1| < 0 and |3 - 5x| >= 0 etc…
The definition of |x| is either positive or negative or zero. But you can assume zero as positive condition.
First be sure the elements under root not having negative sign. example: z + 5 >= 0.
Example |x| : |x + 5| = 2: first condition: when |x + 5| >= 0 then x + 5 = 2, x = - 3.
When |x + 5| < 0 then -x - 5 = 2, x = -7.
