Answer:
x = -2+- sqrt(6)
Step-by-step explanation:
Using completing the square, let x^2+4x-2 = 0 and solve the steps to get the answerx^2 + 4x - 2 =0
add 2 to both sides to get x^2 + 4x = 2
then add 4 to both sides to get x^2 + 4x + 4 = 6
Get the left hand side to the square formate: (x+2)^2 = 6
then simplify x+2 = sqrt(6) or x+2 = -sqrt(6)
so x = sqrt(6) - 2 or x = -sqrt(6) -2
