Tìm x biết : \(\dfrac{x+4}{2014}\)+\(\dfrac{x+3}{2015}=\dfrac{x+2}{2016}+\dfrac{x+1}{2017}\)
Tìm x:
\(\dfrac{x-1}{2014}+\dfrac{x-2}{2013}-\dfrac{x-3}{2012}=\dfrac{x-4}{2011}\)
\(A=\left(\dfrac{1}{5}+\dfrac{2013}{2014}+\dfrac{2015}{2016}+1\right)\left(\dfrac{2013}{2014}+\dfrac{2015}{2016}+\dfrac{1}{10}\right)-\left(\dfrac{1}{5}+\dfrac{2013}{2014}+\dfrac{2015}{2016}\right)\left(\dfrac{2013}{2014}+\dfrac{2015}{2016}+\dfrac{1}{10}+1\right)\)
Tìm x: \(\dfrac{x+4}{2010}+\dfrac{x+3}{2011}=\dfrac{x+2}{2012}+\dfrac{x+1}{2013}\)
\(\dfrac{x+4}{2010}\)+\(\dfrac{x+3}{2011}\)=\(\dfrac{x+2}{2012}\)+\(\dfrac{x+1}{2013}\)
Cho đa thức f(x)=x+x2 - x3 + x4 - ... + x2014 - x2015.

b) E = (5 - 3x)2 - 2013
c) A = 2013 + \(|2x-3|\)
d) B= -1 + \(|\dfrac{1}{2}x-3|\)
e) M = 2015 - \(\dfrac{1}{3+|x-1|}\)
f) N = \(\sqrt{x-3}\) + 2016
Tìm x , biết : (1+1/2+1/3+...+1/2013).x+2013=2014/1+2015/2+...+4026/2013
Tìm Min hoặc Max:
A = \(\dfrac{2015}{18+12\left|x-6\right|}\)
