Answer 1

$\displaystyle\bf\\8)\\\\49am+20mu-14au-70m^{2} =(49am-70m^{2})+(20mu-14au)=\\\\\\=7m(7a-10m)+2u(10m-7a)=7m(7a-10m)-2u(7a-10m)=\\\\\\=(7a-10m)(7m-2u)\\\\\\Otvet:\boxed{(7m-2u)(7a-10m)}\\\\\\9)\\\\uz^{4} +uh^{2} -hz^{4} -h^{5} =(uz^{4} -hz^{4} )+(uh^{4} -h^{5} )=\\\\\\=z^{4} (u-h)+h^{4} (u-h)=(u-h)(z^{4} +h^{4} )\\\\\\Otvet:\boxed{(u-h)(z^{4} +h^{4} )}$
