✔ 最佳答案
x³ + x² = 0x²(x+1) = 0
x = 0, -1
2009-05-14 10:28 pm
x^2 (x+1) = 0
then x = -1 or 0
then x = -1 or 0

x^3 + x^2 = 0
x^2(x + 1) = 0
x^2 = 0
x = 屉0
x = 0
x + 1 = 0
x = -1
â´ x = -1, 0
x^2(x + 1) = 0
x^2 = 0
x = 屉0
x = 0
x + 1 = 0
x = -1
â´ x = -1, 0

x^3 + x^2 =0
x^2( x+1)=0
x^2 =0 , x+1 =0
x=0, -1
x^2( x+1)=0
x^2 =0 , x+1 =0
x=0, -1
