Zeros of a polynomial means its roots
Let the roots are w and z
Then,
wz = 1
d/a = 1
K/3 = 1
K = 3
Please ask if you still have a doubt

atd01:
w x z (product of roots)
.....=1? how
if a quadratic equation is ax2 +bx +c, product of roots = b/a
sorry, its -b/a
so there is a mistake in my answer
ok
actually, the answer is correct
I'm sorry about this, the answer I gave is actually correct. product of roots is c/a if quadratic equation is ax2 + bx + c = 0. Here it says that the two roots are reciprocal of each other. Therefore there product would be 1 . Hence product of roots = c/a = K/3 = 1. K=3
I'm so sorry I left the answer without explanation as I was in a hurry that time
it's ok brother and thanks a lot..
