You can't SOLVE something unless it's an EQUATION. So let's assume you mean the equation
6x² plus 6x plus 6 equals zero (a standard form for equations)
6x² + 6x + 6 = 0
same as
x² + x + 1 = 0 (div both sides by 6)
so
x² + x = -1
Now we can complete the square on THAT thing
x² + x + 1/2 = -1 + 1/2
(x + 1/2)2 = -1/2
Take square root of both sides:
x + 1/2 = √(-1/2)
And, sorry, but you're left with the square root of a negative number.
Have you learned about i, the "imaginary number" equal to the square root of negative 1? Because the right side of your equation is i over √2

Solve by completing square 2x² - 6x plus 7 equals 0?
This quadratic equation has no solutions because the discriminant is less than zero.
Solve this quadratic equation by completing the square. x2 plus 6x 18?
To solve the equation (x^2 + 6x - 18 = 0) by completing the square, first, move 18 to the other side: (x^2 + 6x = 18). Next, take half of the coefficient of (x) (which is 6), square it ((3^2 = 9)), and add it to both sides: (x^2 + 6x + 9 = 27). This can be factored as ((x + 3)^2 = 27). Taking the square root of both sides gives (x + 3 = \pm \sqrt{27}), leading to (x = -3 \pm 3\sqrt{3}).

How do you solve 6x and sup2 plus 6x plus 60 by completing the square?
6x2 + 6x + 60 is an expression, not an equality nor inequality, and so there is nothing that can be solved. Also, the discriminant is negative and so the corresponding equation has no real solutions. All that can be said is:6x2 + 6x + 60 = 6(x2 + x + 10) = 6[(x + 1/2)2 - 1/4 + 10] = 6*[(x + 1/2)2 + 93/4].
