How do you solve by completing the square for #2x^2 + 2x = 0#?
It's a rather strange way to solve it as it is easy to see that
Add 1/2 to both sides to get
Divide both sides by 2 to get
Subtract 1/2 from both sides to get
To complete this square, I need to square half of the coefficient of the 'x', which is 1/2.
