Question

If the one root of the equation 4x² - 2x + p -4 = 0 be the reciprocal of other . Then value of p is

Answer 1

Answer:

P=8

Step-by-step explanation:

Let one root be a, the other root will be 1/a

So now product of roots is c/a

a*1/a =p-4/4

p-4=1*4

p=4+4

P=8

Answer 2

Answer:

p = 8

Step-by-step 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//
