Question

If one root of the equation is the reciprocal of the other then value of k in the equation is

equation:
$(k - 1)x {}^{2} - 10x + 3 = 0$
​

Answer 1

Answer:

let one root be a

and another root be b

So,

a.b = c/a

b is the reciprocal of a

Then,

a.1/a = 3/k-1

1 = 3/k-1

k-1 = 3

k = 3+1

k = 4
