\[x^{8} + x^{6} - 4x^{4} + x^{2} + 1 =\]
\[= x^{8} - 2x^{4} + 1 + x^{6} - 2x^{4} + x^{2} =\]
\[= \left( x^{4} - 1 \right)^{2} + x^{6} - 2x^{4} + x^{2} =\]
\[= \left( x^{4} - 1 \right)^{2} + x^{2}\left( x^{4} - 2x^{2} + 1 \right) =\]
\[= \left( x^{4} - 1 \right)^{2} + x^{2}\left( x^{2} - 1 \right)^{2},\]
\[\left( x^{4} - 1 \right)^{2} + x^{2}\left( x^{2} - 1 \right)^{2} \geq 0 \Longrightarrow\]
\[\Longrightarrow при\ любом\ x.\]
