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:
$$20 x = 60$$
Divide both parts of the equation by 20
We get the answer: x = 3
(x+2)^2 = (x-8)^2
Expand expressions:
4 + x^2 + 4*x = (x-8)^2
(x+2)^2 = 64 + x^2 - 16*x
Reducing, you get:
-60 + 20*x = 0
Move free summands (without x)
from left part to right part, we given:
$$20 x = 60$$
Divide both parts of the equation by 20
x = 60 / (20)
We get the answer: x = 3
