\(\left(2x^2+x-2013\right)^2+4\left(x^2-5x-2012\right)^2=4\left(2x^2+x-2013\right)\left(x^2-5x-2012\right)\)( * )

Đặt \(a=2x^2+x-2013\)

\(\)Đặt \(b=x^2-5x-2012\)

Khi đó ( * ) trở thành:

\(a^2+4b^2=4ab\)

\(\Leftrightarrow a^2+4b^2-4ab=0\)

\(\Leftrightarrow a^2-4ab+4b^2=0\)

\(\Leftrightarrow\left(a-2b\right)^2=0\)

\(\Leftrightarrow a-2b=0\)

\(\Leftrightarrow a=2b\)

\(\Leftrightarrow2x^2+x-2013=2\left(x^2-5x-2012\right)\)

\(\Leftrightarrow2x^2+x-2013-2x^2+10x+4024=0\)

\(\Leftrightarrow11x+2011=0\)

\(\Leftrightarrow x=\dfrac{-2011}{11}\)

Vậy...
