Question

If one root of the equation 4x^ -2x+p-4=0 be the reciprocal of other then find the value of P is

Answer 1

Answer:

p = 8

Explanation:

let the root be y then the reciprocal of the root will be 1/y

so, as we know the product of  roots = c/a

then, product = a(1/a)

                c/a = p-4/4

so,

      a*1/a = p-4/4

            1 = p-4/4

           4 = p-4

           p = 8//

hope this helps you
