1. Answer:

   Real and equal

   Step-by-step explanation:

   Given Discriminant D=b

   2

   −4ac=0

   Let ax

   2

   +bx+c=0 be a standard quadratic

   equation then roots are –

   x=

   2a

   −b±

   b

   2

   −4ac

   =

   2a

   −b

   ,

   2a

   −b

   Hence roots are real and equal.
