The solution
Detail solution
Given the equation:
$$\frac{\left(x - 2\right)^{2}}{x + 1} = 0$$
the denominator
$$x + 1$$
then
Because the right side of the equation is zero, then the solution of the equation is exists if at least one of the multipliers in the left side of the equation equal to zero.
We get the equations
$$x - 2 = 0$$
solve the resulting equation:
1.
$$x - 2 = 0$$
Move free summands (without x)
from left part to right part, we given:
$$x = 2$$
We get the answer: x1 = 2
but
The final answer:
$$x_{1} = 2$$
$$\frac{\left(x - 2\right)^{2}}{x + 1} = 0$$
the denominator
$$x + 1$$
then
x is not equal to -1
