Question

if the sum of the zero of the polynomial f(x)=2×3-3k×2+4x-5 is 6, then the value of k is​

Answer 1

Answer:

Hii bruh,

Answer is given below ⬇️

Step-by-step explanation:

f(x) = 2x3 – 3kx2 + 4x – 5

Sum of the zeros of the polynomial = 6

Let x, y and z be the zeroes than,

x + y + z = 6……Equation (i)

x + y + z = – b/a = – ( – 3k)/2

From Eq. (i) we get, 3k/2 = 6 k/2 = 6/3

k = 2×2 = 4.
