# How do you write y= -2(x+1)^2+3 in standard form?

standart form of a second degree polynomial is $y = a {x}^{2} + b x + c$
$y = - 2 {\left(x + 1\right)}^{2} + 3$
$y = - 2 \left(x + 1\right) \left(x + 1\right) + 3$
$y = - 2 \left({x}^{2} + 2 x + 1\right) + 3$
$y = - 2 {x}^{2} - 4 x - 2 + 3$
$y = - 2 {x}^{2} - 4 x + 1$
