Question

If the zeroes of the polynomial px2+qx+3 are reciprocal to each other, then :
(a) q=3 (b) p=3 (c) p-q=0 (d) 3p+q=0

Answer 1

$\underline{\textbf{Given:}}$

$\mathsf{Zeroes\;of\;px^2+qx+3\;are\;reciprocal\;to}$

$\textsf{each other}$

$\underline{\textbf{To find:}}$

$\textsf{The suitable condition for zeroes to be reciprocal}$

$\underline{\textbf{Solution:}}$

$\mathsf{Consider,\;px^2+qx+3}$

$\textsf{Since the zeroes are reciprocal to each other,}$

$\mathsf{we\;have\;Product\;of\;zeroes=1}$

$\implies\mathsf{\dfrac{3}{p}=1}$

$\implies\boxed{\mathsf{p=3}}$

$\underline{\textbf{Answer:}}$

$\mathsf{Option\;(b)\;is\;correct}$
