Question

$\huge \underline\mathfrak \red{question} \star$Write the value of. -(a+b)^2 + (a-b)^2

​

Answer 1

Correct Question :

• ${\sf{Write \:the \:value\: of\: –\: \bigg(a + b\bigg)^2 + \bigg(a - b\bigg)^2}}$

A N S W E R :

• ${\sf{2\bigg(a^2 + b^2\bigg)}}$

E X P L A N A T I O N :

$\large\star$ As we know that,

$\large\dag$ Formula Used :

• $\boxed{\sf{\bigg(a + b\bigg)^2 \:+\: \bigg(a - b\bigg)^2}}$$\large\dag$

:$\implies{\sf{a^2 \:+ \:b^2 + \cancel{2ab} \:+\: a^2 + b^2 \: -\: \cancel{2ab}}}$

:$\implies{\sf{2a^2 \: + \: 2b^2}}$

:$\implies{\underline{\boxed{\frak{\pink{2\bigg(a^2 + b^2\bigg)}}}}}$★

Hence,

• ${\underline{\sf{The \: value \: of \; \bf{2\bigg(a^2 + b^2\bigg)}}}}$

$~~~~~~~~$${\underline{\bf{NOTE \; \bf{:} \: \sf{Pic \: is \: in \: the \: attached !}}}}$

$~~~~$$\qquad\quad\therefore{\underline{\textsf{\textbf{Hence, Proved!}}}}$
