Find the solution of the equation 1/2x^2 -x +5=0

If you would like to solve the equation 1/2 * x^2 - x + 5 = 0, you can do this using the following steps:

1/2 * x^2 - x + 5 = 0      /*2
x^2 - 2x + 10 = 0
(x - 1)^2 + 9 = 0
1. x = 1 - 3 * i
2. x = 1 + 3 * i

The correct result would be x = 1 - 3 * i and x = 1 + 3 * i.

It is 7 because it is the absolute value
