Let ( , ) be the roots of the equation (x^2-|a| x-|b|=0 ) such that (| | < | | ). If (|a| < -1 ), then the positive root of ( _ 여 ( x^2 ^2 )-1=0 ), is

Options

  1. A( < | | )
  2. B( < )
  3. C( < )
  4. D( > )

Correct answer

D. ( > )

Step-by-step solution

Given, ( _ | | ( x^2 ^2 )=1 ) ( x^2 ^2 =| | x^2= ^2| | ) and ( , ) are roots of equation (x^2-|a| x-|b|=0 )...(i) so, ( + =-|a| [as < 0 ] )
