If x belongs set of real numbers, find the maximum value of [tex]2(a-x)(x+\sqrt{x^{2}+b^{2}})[/tex]
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 can't make head or tail out of it.
