Answer:
   x^2 -4x +2 = 0
Step-by-step explanation:
The other root is the conjugate of the given one, so is 2-√2. The quadratic equation in factored form is then ...
   (x -2-√2)(x -2+√2) = 0
Expanding this, we get ...
   (x -2)^2 -(√2)^2 = 0
   x^2 -4x +4 -2 = 0
   x^2 -4x +2 = 0 . . . . the equation you're looking for
