The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$4 x = -625$$
Divide both parts of the equation by 4
We get the answer: x = -625/4
25^2+4*x = 0
Move free summands (without x)
from left part to right part, we given:
$$4 x = -625$$
Divide both parts of the equation by 4
x = -625 / (4)
We get the answer: x = -625/4
