Answer 1

Answer:

Step-by-step explanation:

Given that: if the two zeros of the quadratic polynomial 7x²-15x-k are reciprocals of each other.

To find: Value of k

Solution:

Let

are the zeroes of polynomial.

relation between coefficient of polynomial with its zeros are given by

where a,b and C are coefficient of x²,x and constant term respectively.

here a=7,b=-15,c=-k

Here in the question given that, zeros are reciprocals to each other,thus if one zero is

then other zero is

Now put the values in eq2

Thus,

Value of k is -7.

Hope it helps you.
