Question

if the sum of the zeroes of the polynomial f(x) = 2x cube - 3kx +4x -5 is 6 then the value of k is?

Answer 1

Step-by-step explanation:

let alpha, beta, gamma roots of the equation 2 x cube minus 3 X square + 4 x minus 5. alpha + beta + gamma=6

3k/2=6

k=4

hope it helps

Answer 2

Answer:

let alpha,                   beta,                         gamma roots of the                                equation                       2 x cube minus 3 X square + 4 x minus 5.                       alpha     +     beta    +     gamma    =    6

3k/2=6

k=4
