Question

if one root of the equation 5x²+13x+k=0 is reciprocal of other, then what is the value of 'k'​

Answer 1

Answer:

If one root of the polynomial f(x) =5x²+13x+k is reciprocal of the other, then what is ... Here we have the equation 5x²+ 13x + k = 0 ... If -1 is a zero of the polynomial p(x) =ax3-x2+x+4, what is the value of a ?

Answer 2

Step-by-step explanation:

Let one root be p and other root be 1/p.

We know, Product of roots = c/a = k/5

Also, Product of roots = p×1/p = 1

Hence,

k/5 = 1

=) k=5

Hence the value of k is 5
