Answer 1

$good \: \: morning \: \: \\ \\ the \: \: given \: \: equation \: \: has \: 5 \: roots \: \\ \\ x = 0 \: \: \: \: or \: \: \: (x + 5) = 0 \: \: \: \: \\ \\ \\ or \: \: \: \: \: 3x {}^{2} + 12x + 9 = 0 \\ \\ \\ 3x {}^{2} + 9x + 3x + 9 = 0 \\ \\ 3x(x + 3) + 3(x + 3) = 0 \\ \\ \\ (3x + 3) = 0 \: \: \: or \: \: \: (x + 3) = 0 \\ \\ \\ \\ so \: the \: possible \: values \: of \: x \: are \: \: \\ \\ \\1) \: \: \: x = 0 \\ \\ 2) \: \: \: x = - 5 \\ \\ 3) \: \: \: x = - 1 \\ \\ 4) \: \: \: x = - 3$
