\[x^{5} + 5x^{3} - 6x^{2} = 0\]
\[x^{2}\left( x^{3} + 5x - 6 \right) = 0\]
\[x^{2}\left( x^{3} - x + x + 5x - 6 \right) = 0\]
\[1)\ x^{2} = 0\]
\[x = 0.\]
\[2)\ \left( x^{3} - x \right) + (6x - 6) = 0\]
\[x\left( x^{2} - 1 \right) + 6(x - 1) = 0\]
\[x(x - 1)(x + 1) + 6(x - 1) = 0\]
\[(x - 1)\left( x^{2} + x + 6 \right) = 0\]
\[x - 1 = 0\]
\[x = 1.\]
\[x^{2} + x + 6 = 0\]
\[D = 1 - 24 = - 23 < 0\]
\[нет\ корней.\]
\[Ответ:x = 0;x = 1.\]
