If one zero of the polynomial f(x) = 15x^2+14x-k is

k = -15

Step-by-step explanation:

The given question says that,

If one zero of the polynomial  is reciprocal of the other. We need to find the value of k.

Let be one of the zero then 1/ will be another zero of the polynomial.

We now that,

Product of zeroes = c/a

We have, c = -k and a = 15

So,

So, the value of k is equal to (-15).

b
