The solution
You have entered
[src]
2 (x - 6) - x*(x + 8) = 2
$$- x \left(x + 8\right) + \left(x - 6\right)^{2} = 2$$
Detail solution
Given the equation:
Expand expressions:
Reducing, you get:
Move free summands (without x)
from left part to right part, we given:
$$- 20 x = -34$$
Divide both parts of the equation by -20
We get the answer: x = 17/10
(x-6)^2-x*(x+8) = 2
Expand expressions:
36 + x^2 - 12*x - x*(x + 8) = 2
36 + x^2 - 12*x - x^2 - 8*x = 2
Reducing, you get:
34 - 20*x = 0
Move free summands (without x)
from left part to right part, we given:
$$- 20 x = -34$$
Divide both parts of the equation by -20
x = -34 / (-20)
We get the answer: x = 17/10
