Here in this question a is not real how we will find the roots

Choose the correct answer:
1 If   a x 2 + b x + c = 0   ( a ,   c ≠ 0 ,
  b ,   c ∈ R ) ,   then   x  
equals
1   - b ± b 2 - a c 2 a 2   - b ± b 2 - 2 a
c 2 a 3   2 c - b ± b 2 - 4 a c 4   - b ± b
2 - 4 a c 2 a

Dear Student,
  The roots of any quadratic equation(ax2+bx+c=0) can be found by using formula,       x=-b±b2-4ac2a, There is no correct option
