Question

If one root of 3x2 + 2x + k = 0) is the
reciprocal of the other, then the value of
kis
1) 3
2)-3
3)2
4) 6​

Answer 1

Step-by-step explanation:

Let the roots of equation be alpha and other root be 1/alpha

Given 3x^2+2x+k=0.........where a=3

b=2

c=k

Now,

Product of zeroes = c/a

alpha x 1/alpha = k/3

1=k/3

Therefore...... K=3
