Explicación paso a paso:

$1.$ $x^{2}+10x=0$

$x=0\\x=-10$

$2.\ 8x^{2}-20x=0\\x=\frac{5}{2}\\x=0$

$3.\ 4x^{2}+20=0\\4(x^{2}+5)=0$

$4.\ 4x^{2}+40x=0\\x=0\\x=-10$

$5.\ 6x^{2}-25x=0\\x=\frac{25}{6}\\x=0$

$6.\ x^{2}-36=0\\x=6\\x=-6$

$7.\ x^{2}-5=0\\x=+\sqrt{5} \\x^{2}-5$

$8.\ x^{2}+8=0\\x=+\frac{\sqrt{-32}}{2}$

$9.\ x^{2}-40x=0\\x=40\\x=0$

$10.\ x^{2}-158=0\\x=\sqrt{158},-\sqrt{158}$
