Answer 2

$\huge{\purple{\underline{\mathtt{QUESTION}}}}$

$\bf{x2 + 2 = 0}$ , find $\bf{x}$

$\huge{\blue{\underline{\mathtt{ANSWER}}}}$

$\implies \bf{x2 + 2 = 0 }$

$\implies \bf{x2 = 0 - 2 }$

$\implies \bf{x2 = -2}$

$\implies \bf{x = \frac{-2}{2}}$

$\implies \bf{x = -1}$

_________________________________

Proof of the expression :-

$\therefore L.H.S.$ $\longrightarrow$

$\implies x2 + 2$

$\implies (-1)2 + 2$ [ $\because x = -1$ ]

$\implies -2 + 2$

$\implies 0 = R.H.S.$
