what formula should i use to solve this quadratic formula?
2x2 + 4x + 2 = 0.

There are different ways to solve a quadratic equation. The problem can most easily be solved by factoring.
2x²+4x+2 = 0
2(x²+2x+1) = 0
2(x+1)² = 0
therefore x+1=0.
Can you take it from here? 
I can't type in the formula because of the typing options but go to purplemath or mathwarehouse to get help.

actualy you can factor out 2
