(2009-x)^2+(2009-x)×(x-2010)+(x-2010)^2/(2009)^2-(2009-x)×(x-2010)+(x-2010)^2=19/49
tìm x biết :
(2009 - x^2) + ( 2009 - x^2)( x - 2010) + ( x - 2010) / (2009 - x^2) - ( 2009 - x^2)( x - 2010) + ( x - 2010 ) = 19/49
Tìm x : (2009-x)2+(2009-x)(x-2010)+(x-2010)2/(2009-x)2-(2009-x)(x-2010)+(x-2010)2=19/49

Tìm x biết: (2009-x)2 + (2009-x)(x-2010) + (x-2010)2/(2009-x)2 - (2009-x)(x-2010) + (x-2010)2 = 19/49
Tìm x biết: (2009-x)2 + (2009-x)(x-2010) + (x-2010)2/(2009-x)2 - (2009-x)(x-2010) + (x-2010)2 = 19/49
(2009-x)2+(2009-x)(x-2010)+(x-2010)2/(2009-x)2-(2009-x)(x-2010)+(x-2010)2=19/49
