Answer 2

Answer:

$\underline \bold{{x }^{2} + 5x + 6 = 0}$

$→ \: {x}^{2} + 3x + 2x + 6 = 0$

$→ \: x(x + 3) + 2(x + 3) = 0$

$→ \: (x + 3)(x + 2) = 0$

$→x + 3 = 0 \: \: \: \: \: \: \: \: \: \: \: \: \: \: or \: \: \: \: \: x + 2 = 0$

$→ \boxed{ \bold{x = - 3} }\: \: \: \: \: \: \: \: \: \: \: \: or \: \: → \boxed{\bold{x = - 2}}$
