Answer 2

$\huge \red{ \boxed{ \bf{ \ulcorner{ \mid{ \overline{ \underline{ANSWER}}}}}\mid }}$

$\huge \pink{ \mid{ \overline{ \underline{ \mathbb{GI} \mathit{V}\mathfrak{EN}}}} \mid}$

The Solution is as follows

$= > {x}^{2} + 7x + 12 \\ = > {x}^{2} + 4x + 3x + 12 \\ = > x(x + 4) + 3(x + 4) \\ = > (x + 3)(x + 4) \\ = > so \\ = > x = - 3 \: and \: - 4$
