$\huge \frak{ \color{blue}{ \underline{ \underline{ \color{blue}{✿}{ \pink{Question}}}}}}$

Simplify (a + b + c) ( a + b + c)

$\huge \frak{ \pink{ \underline{ \underline{ \pink{✿}{ \color{blue}{Answer}}}}}}$

$⇒ \sf(a + b + c)(a + b + c)$

$⇒ \sf \: a(a + b + c) + b(a + b + c) + c(a + b + c)$

$⇒ \sf \: a {}^{2} + ab + ac + ab + b {}^{2} + bc + ac + bc + c {}^{2}$

$⇒ \sf \: a {}^{2} + b {}^{2} + c {}^{2} + ab + ab + bc + bc + ac + ac$

$⇒ \sf \: a {}^{2} + b {}^{2} + c {}^{2} + 2ab + 2bc + 2ac$
