$y = ( {x}^(2) + 2x + 1) - 1$

$y = ({x + 1})^(2) - 1$

$y = ({x + 1})^(2) - ({1})^(2)$

We're done now but I have something to tell...

##############################

Hint :

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

##############################

$y = ( \: (x + 1) + 1)( \: (x + 1) - 1) \\$

y = (x + 2)(x)
