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:
$$30 x = -75$$
Divide both parts of the equation by 30
We get the answer: x = -5/2
(x+10)^2 = (5-x)^2
Expand expressions:
100 + x^2 + 20*x = (5-x)^2
(x+10)^2 = 25 + x^2 - 10*x
Reducing, you get:
75 + 30*x = 0
Move free summands (without x)
from left part to right part, we given:
$$30 x = -75$$
Divide both parts of the equation by 30
x = -75 / (30)
We get the answer: x = -5/2
