If one root of 5x2 + 13x + k = 0 be the reciprocal of the other root then the value of k is
Let the roots of equation be 
than other root will be 
Product of two roots = 
Product of the roots = 
For the given equation 5x2 + 13x + k = 0
a = 5 b = 13 c = k comparing with ax2 + bx + c = 0
Product of the roots 
k = 5
