The solution
You have entered
[src]
2 2 2 (x - 2) + (x - 3) = 2*x
$$\left(x - 3\right)^{2} + \left(x - 2\right)^{2} = 2 x^{2}$$
Detail solution
Given the equation:
Expand expressions:
Reducing, you get:
Move free summands (without x)
from left part to right part, we given:
$$- 10 x = -13$$
Divide both parts of the equation by -10
We get the answer: x = 13/10
(x-2)^2+(x-3)^2 = 2*x^2
Expand expressions:
4 + x^2 - 4*x + (x - 3)^2 = 2*x^2
4 + x^2 - 4*x + 9 + x^2 - 6*x = 2*x^2
Reducing, you get:
13 - 10*x = 0
Move free summands (without x)
from left part to right part, we given:
$$- 10 x = -13$$
Divide both parts of the equation by -10
x = -13 / (-10)
We get the answer: x = 13/10
