(x+2)³+1=0,求x的值,(x+2)³+1=0,求x的值,(x+2)³+1=0,求x的值,(x+2)³+1=0,求x的值,
(x+2)³+1=0,求x的值,
(x+2)³+1=0,求x的值,
(x+2)³+1=0,求x的值,
(x+2)³+1=0,求x的值,

(x+2)³+1=0,求x的值,(x+2)³+1=0,求x的值,(x+2)³+1=0,求x的值,(x+2)³+1=0,求x的值,
(x+2)³+1=0
(x+2)³=-1
x+2=-1
x=-3

(x+2)³+1=0
(x+2)³=-1
x+2=-1
x=-3

(x+2)^3=-1
x+2=-1
x=-3

解得x+2=-1
即 x=-3

(x+2)的3次方等于-1,x=-1
