Question

If -2 is zero of the polynomial p(y)=3-ky then find the value of k.​

Answer 1

Answer:

If -2 is zero of polynomial then the value of p(y)=3-ky

3-ky=0

then y=-2

putting this value in the equation

We get,

3-k(-2)=0

3-2k=0

-2k= -3

k= 3/2

The Value of k= 3/2

this is the required answer.
