Answer 1

Answer:

(x+6) (x + 3)

Step-by-step explanation:

x2 + 9x + 18

= x2 + 6x + 3x + 18

= x(x + 6) + 3 (x +6)

= (x+6) (x + 3)

Answer 2

☘️$\Large{\blue{\bold{Solution:}}}$

$→\; {x}^{2} + 9x + 18 = 0$

$→\; {x}^{2} + 6x + 3x + 18 = 0$

$→\: x(x + 6) + 3(x + 6) = 0$

$→\; (x + 3)(x + 6) = 0$

$→\; {\red{\sf{x = - 3 \: (or) - 6}}}$
