x2 + 8x + 16
$x2 + 8x + 16$
​

Answer 1

${\tt{\purple{\underline{\underline{\huge{Answer:}}}}}}$

$\implies\sf {x}^{2} + 8x + 16 = 0$

$\implies\sf {x}^{2} + 4x + 4x + 16 = 0$

$\implies\sf \: x(x + 4) + 4(x + 4) = 0$

$\implies\sf(x + 4) = 0 \: \: or \: \: (x + 4) = 0$

$\implies\sf \: x = - 4 \: \: or \: \: x = - 4$
