The solution
Detail solution
Given the equation:
Expand expressions:
Reducing, you get:
Move free summands (without x)
from left part to right part, we given:
$$6 x = -3$$
Divide both parts of the equation by 6
We get the answer: x = -1/2
(x+2)^2 = (1-x)^2
Expand expressions:
4 + x^2 + 4*x = (1-x)^2
(x+2)^2 = 1 + x^2 - 2*x
Reducing, you get:
3 + 6*x = 0
Move free summands (without x)
from left part to right part, we given:
$$6 x = -3$$
Divide both parts of the equation by 6
x = -3 / (6)
We get the answer: x = -1/2
