Answer:

  x² -4x +1 = 0

Step-by-step explanation:

For roots p and q, the factored form of the equation is ...

  (x -p)(x -q) = 0

The expanded form of this is ...

  x² -(p+q)x +pq = 0

So, we can find the coefficients of the quadratic by finding the sum and product of the factors.

  -b = (2 -√3) + 1/(2 -√3) = (2 -√3) +(2 +√3)/((2-√3)(2+√3)) = 4

  c = (2 -√3)/(2 -√3) = 1

So, the quadratic is ...

  x² -4x +1 = 0
