$\huge \underline {\fbox{Answer}}$

$\large \underline{\underline {\frak{ \color{red}Given::}}}$

$\mapsto \sf{(x + 4)(x + 7)}$

$\large \underline{\underline {\frak{ \color{blue}To \: find::}}}$

${ \leadsto \sf{Find \: the \: product \: of \: (x + 4)(x + 7).}}$

$\large \underline{\underline {\frak{ \color{indigo}Identity \: required::}}}$

${\rightarrow \sf{(x + a)(x + b) = {x}^{2} + (a + b)x + ab }}$

$\large \underline{\underline {\frak{ \color{indio}According \: to \: Question::}}}$

${\implies \sf{(x + a)(x + b) = {x}^{2} + (a + b)x + ab }}$

${\implies \sf{(x + 4)(x + 7) = {(x)}^{2} + (4 + 7)x +4 \times 7 }}$

${\implies \sf{(x + 4)(x + 7) = {x}^{2} + (11)x +28}}$

${\implies \sf{(x + 4)(x + 7) = {x}^{2} + 11x +28}}$

$\bf{Hence,}$

${ \longmapsto\sf{Product \: of \: (x + 4)(x + 7) \: is \: {x}^{2} + 11x +28.}}$
