What do you want? Combine like terms, maybe? You have four terms, so maybe it is already simplified. Factorize? Each of the four terms contains a factor of sqrt%28b%29.

Maybe you may put as %283a%2Asqrt%283%29%2Ba%2Asqrt%285%29%2Ba%2Asqrt%283%29-4b%2Asqrt%285%29%29%2Asqrt%28b%29.

What more? Move the terms of sqrt%283%29 and sqrt%285%29 ?
%283a%2Asqrt%283%29%2Ba%2Asqrt%283%29%2Ba%2Asqrt%285%29-4b%2Asqrt%285%29%29%2Asqrt%28b%29
%284a%2Asqrt%283%29%2B%28a-4b%29sqrt%285%29%29%2Asqrt%28b%29
