✔ 最佳答案
can be ZERO, or ONE. Only DIVIDING by zero is undefined.

x² = x
x² - x = x - x
x² - x = 0
x (x - 1) = 0
x = 0 or x - 1 = 0
x = 0, 1
x² - x = x - x
x² - x = 0
x (x - 1) = 0
x = 0 or x - 1 = 0
x = 0, 1

x^2 = x
x^2 - x = 0
x(x - 1) = 0 ---> x = 0 or x = 1.
The only way you'd get undefined is if you got a denominator in play, and clearly that's not the case.
x^2 - x = 0

x^2 = x
==> x^2 -x = 0
==> x(x-1) = 0
so x = 0 or x = 1
==> x^2 -x = 0
==> x(x-1) = 0
so x = 0 or x = 1

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

x² - x = 0
x ( x - 1 ) = 0
x = 0 , x = 1
x ( x - 1 ) = 0
x = 0 , x = 1

X^2 = x
X = 1
X = 1
