The solution
Detail solution
Given the equation:
$$\frac{x^{2} - 1}{x - 1} = 0$$
transform:
$$\frac{\left(x - 1\right) \left(x + 1\right)}{x - 1} = 0$$
$$x + 1 = 0$$
Move free summands (without x)
from left part to right part, we given:
$$x = -1$$
We get the answer: x = -1
$$\frac{x^{2} - 1}{x - 1} = 0$$
transform:
$$\frac{\left(x - 1\right) \left(x + 1\right)}{x - 1} = 0$$
$$x + 1 = 0$$
Move free summands (without x)
from left part to right part, we given:
$$x = -1$$
