Question

If one root of px^2+qx+r-o is reciprocal of the other root then,
B)q=r
C) p=r
А) p=q
D)p=r=q​

Answer 1

Answer:

C) p= r

Step-by-step explanation:

$let \: \: roots \: \: be \: \: \alpha \: \: and \: \: \beta . \\ \alpha = \frac{1}{ \beta } \: \: (given) \\ \alpha \beta = 1 \\ \frac{ c}{a} = 1 \\ \frac{r}{p} = 1 \\ r = p \\i.e. \: p = r$
