By applying mathematical generality , we can view that , after vanishing " k " and transforming the equation to complete standard cubic equation , we can have atleast two distinct positive roots aslike -

After vanishing " k " [ k = 0 ]

x³ - 27x = 0

x [ x² - 27 ] = 0

x = 0 , x = ±3√3

Solutions obtained after implementing GENERALITY is " 3 "

HENCE , AFTER VANISHED CONSTANT , WE CAN HAVE ATLEAST TWO POSITIVE ROOTS 0 AND 3√3

THEREFORE , VALUE OF K = 0
