If one root of th

Answer :

3x2 + px + 4 = 0


3(2/3)2 + p(2/3) + 4 = 0


4/3 + 2p/3 + 4 = 0


p = -8


3x2 - 8x + 4 = 0


By middle term splitting,


3x2 - 6x - 2x + 4 = 0


x = 2/3 or x = 2


Hence, x = 2


OR


α + β = 5 ----(1)


α – β = 1 ----(2)


Solving (1) and (2), we get


α = 3 and β = 2


also, αβ = 6


or 3(k - 1) = 6


k – 1 = 2


k = 3
