    m x 2 + n x 2 + p x 2

= ( m + n + p ) x 2

=       2009     x 2  

=         4018

\(M=1-\frac{2}{x}+\frac{2015}{x^2}\)

Đặt y = 1/x

=> M = 1 - 2y + 2015y² = 2015.(y² - 2.y .\(\frac{1}{2015}\) + \(\frac{1}{2015^2}\)) - \(\frac{1}{2015}\) + 1 = 2015.(y - \(\frac{1}{2015}\))² + \(\frac{2014}{2015}\)\(\ge\) 0 +  \(\frac{2014}{2015}\) với mọi y

Vậy Min M = \(\frac{2014}{2015}\) khi y - \(\frac{1}{2015}\) = 0 <=> y = \(\frac{1}{2015}\)<=> 1/x = \(\frac{1}{2015}\) <=> x = 2015
