Question

FIND THE VALUE OF (X+2) WHOLE SQUARE BY 2?​

Answer 1

$\huge\pink{\boxed{\green{\mathfrak{\overbrace{\underbrace{\fcolorbox{red}{aqua}{\underline{\pink{☆Answer☆}}}}}}}}}$

$= \frac{ {(x + 2)}^{2} }{2}$

by using identity,

$= \frac{ {x}^{2} + 4x + 4}{2}$

$\huge\mathcal\pink{please}$   $\huge\mathcal\pink{drop}$   $\huge\mathcal\pink{some}$   $\huge\mathcal\pink{thanks}$   $\huge\mathcal\pink{dear.}$

$\huge\mathcal\red{I}$   $\huge\mathcal\red{will}$   $\huge\mathcal\red{return}$   $\huge\mathcal\red{you}$   $\huge\mathcal\red{back.}$

Answer 2

$\huge\boxed{\fcolorbox{black}{pink}{Solution}}$

$({x+ 2})^{2}$

$using \: identity, \: ( {a + b})^{2}$

$( {a + b})^{2} = {a}^{2} + {b}^{2} + 2ab$

$( {x + 2})^{2} = {x}^{2} + {2}^{2} + 2 \times x \times 2$

$= {x}^{2} + 4 + 4x$

$= \: {x}^{2} + 4x \: + \: 4$
