Question

write the zero of the polynomial x square + 2x+1

Answer 1

x(x+1)+2(x+1)
(x+1)+2+x

Answer 2

$hey \: mate \: here \: is \: your\: answer$
$x {}^{2} + 2x + 1$
$x {}^{2} + (1 + 1)x + 1$
$x {}^{2} + x + x + 1$
$x(x + 1) + 1(x + 1)$
$(x + 1)(x + 1)$




$x + 1 = 0 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: x + 1 = 0$
$x = - 1 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: x = - 1$
$hence \: the \: zeros \: of \: the \: polynomial \: are \:$

$- 1 \: and \: - 1$
$hope \: it \: helps.....$
