MCQ - 501-9233

Question:

If one root of 5x² + 13x + k = 0 be the reciprocal of the other root then the value of k is

Correct Answer: D

Explanation:

Let the roots of equation be a than other root will be $\frac{1}{a}$
Product of two roots = $\frac{1}{a}$ a = 1
Product of the roots = $\frac{c}{a}$
For the given equation 5x² + 13x + k = 0
a = 5 b = 13 c = k comparing with ax²+ bx + c = 0
Product of the roots = $\frac{c}{a}$ = 1
k = 5
