The solution
Detail solution
Given the equation:
$$\frac{z - 1}{z \left(z - 1\right)} = 0$$
Multiply the equation sides by the denominator z
we get:
Move free summands (without z)
from left part to right part, we given:
$$0 = -1$$
This equation has no roots
$$\frac{z - 1}{z \left(z - 1\right)} = 0$$
Multiply the equation sides by the denominator z
we get:
False
Move free summands (without z)
from left part to right part, we given:
