Answer 1

Answer:

As it is cubic polynomial

$\alpha \beta \gamma = - d \: upon \: a$

$let \: \alpha = x \\ \beta = y \\ and \: as \: - 1 \: is \: a \: zero \: of \: cubic \: poly. \\ \gamma = - 1$

$(x)(y)( - 1) = - c \: upon \: 1$

$as \: - d = - c \\ and \: a = 1$

$therefore \\ (x)(y) = - c \: upon \: - 1 \\ (x)(y) = c \\ therefore \\ \alpha \beta = c \: \: \:$

as

$\alpha = x \: and \: \beta = y$

Therefore product of other two zeroes is c
