Question

If one zero of the polynomial 5x2 + 10x = k is reciprocal of the other than find
the value of k
OR​

Answer 1

Answer:

Let one root of the given that other zero is Reciprocal the one zero.

So,

Other zero=1/Alpa.

Given polynomial is 5x^2 +13x+k=0.

Here,

A=coefficient of x^2

B=coefficient of x

And,C=constant term.

Product of zeroes =C/A

Alpha ×1/Alpha =K/5

1=K/5

K=5

Then,

We get k=5.
