$\boxed{ \underline{ \bf{ \bullet \: the \: value \: of \: (x + 3)(x + 3) \: at \: x = 4}}}$

$\huge\boxed{\fcolorbox{Blue}{Red}{Correct \: Answer}}$

$\ \ggg \bf{(x + 3)(x + 3)}$

$\: \ggg \bf{(x(x + 3) + 3(x + 3)})$

$\: \ggg \bf{ ({x}^{2} + 3x + 3x + 9)}$

$\: \: \ggg \bf{ {x}^{2} + 6x + 9}$

$\red \bigstar \large \sf{ \color{lime} \ \: put \: the \: value \: of \: x = 4 \: in \: equation}$

$\: \ggg \bf{( {(4)}^{2} + 6(4) + 9})$

$\: \: \ggg \bf{16 + 24 + 9}$

$\: \ggg \bf{40 + 9}$

$\: \ggg{ \bf{49}}$
