D)
Alfa - Beta = √{( Alfa + Beta )² - 4Alaf × Beta}
Alfa + Beta = -q/p
And
Alfa × Beta = r/p
=>
Alfa + Beta = 4 ( Alfa × Beta )
=>
-q/p = 4r/p
=>
q = - 4r
=>
2q = p + r
=>
-8r - r = p
=>
p = -9r
=>
Alfa - Beta = √{(q²/p²) - 4 r/p }
=>
Alfa - Beta = √{(16r² /81r²) +4r/9r }
=>
Alfa - Beta = √{468/81×9)
=>
Alfa - Beta = √{52/81}
=>
Alfa - Beta = √(52)/9
=>
Alfa - Beta = 2√(13)/9
