 5x^(2m) 8x^m +8  =8(5x^(3m) +1)
$$\:\mathrm{5}{x}^{\mathrm{2}{m}} \mathrm{8}{x}^{{m}} +\mathrm{8} \\ $$$$=\mathrm{8}\left(\mathrm{5}{x}^{\mathrm{3}{m}} +\mathrm{1}\right) \\ $$

=8(5^(1/3) x^m +1)(5^(2/3) x^(2m) −5^(1/3) x^m +1)
$$=\mathrm{8}\left(\mathrm{5}^{\mathrm{1}/\mathrm{3}} {x}^{{m}} +\mathrm{1}\right)\left(\mathrm{5}^{\mathrm{2}/\mathrm{3}} {x}^{\mathrm{2}{m}} −\mathrm{5}^{\mathrm{1}/\mathrm{3}} {x}^{{m}} +\mathrm{1}\right) \\ $$
