(х+6)(х³-8) = 0
(х+6)*(х³-2³) = 0
(х+6)*(х-2)(х²+2х+4) = 0
х+6 = 0
х = -6
х-2 = 0
х = 2
<span>х²+2х+4= 0
</span>D = 4-16 = -12 - корней нет
Ответ:-6; 2
Можно по-другому:
(х+6)*(х³-8) = 0
х+6 = 0
х = -6
х³-8 = 0
х³ = 8
х = 2
10-4х+3-9х+2+6х-9+7х-6=(10+3+2-9-6)+(-4х-9х+6х+7х)=0
21/2+35 3/3+37 6/3=38 1/3
