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? - Aug 28th 2011, 09:40 AManonimnystefyRe: Radicals Help
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! - Aug 28th 2011, 09:46 AMgrandepuntoRe: Radicals Help
