(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

If x belongs set of real numbers, find the maximum value of [tex]2(a-x)(x+\sqrt{x^{2}+b^{2}})[/tex]

3. The attempt at a solution

All that I could do was to try and diffrentiate the above expression but it yields a polynomial of degree 4. A hint to this question is that it belongs to the Quadratic Equations Chapter. And the answer to th above question is [tex]a^{2}+b^{2}[/tex]

Please help me. I cant make head or tail out of it.
