multiply all sides by 2x^2
1 + 4x^3 + 6x^2 = 0
let y = x^2
1 + 4y^2 + 6y=0
4y^2 + 6y + 1 = 0
Apply the quadratic formula then sqrt the answer to get the answer

the way you typed it,
multiply each term by 2
x^2 + 4x + 6 = 0
complete the square ...
x^2 + 4x + 4 = -6+4
(x+2)^2 = -2
x+2 = ± √-2
x = -2 ± i√2
