Description on how to solve this would be much appreciated.

hi grande punto

that is not an equation,so you can't really solve it!

if you want to simplify it then:

thanks very much for the response. sorry my english in not very good because i study in italian. i meant simplify.

can u please help me understand this. when you simplify, shouldn't it be 4√  (x^2 + 1 + 1/2)^2 how did u get rid of the 1?

try expanding (x^2 + 1/2)^2,and then try expanding (x^2 +1+1/2)^2=(x^2 + 3/2)^2. See what you get.

Also i didn't realise that you had a in your radical and not x.sorry about that!

ok thanks again. i better get back to studying the basics i guess.

you're welcome!
