Answer 1

Answer:D

Step-by-step explanation:

1.Since the equation has a complex, its other root will be the conjugate.

2.With the two roots, solve for the quadratic equation

x=1/(1+√3) and x=1/(1-√3)

x+x√3=1 and x√3=1

x+x√3-1=0 and x-x√3-1=0

(x+x√3-1)(x-x√3-1)=0

x²-x²√3-x+x²√3-3x²-x√3 -x+x√3+1=0

Cancelling out the necessary values we are left with

-2x²-2x+1=0

...2x²+2x-1=0
