Question 1060935
(a)  You already have the factorization, so this part of the question is already shown.


(b)  First try simplifying, ....
{{{y=-2(x-3-i)(x-3+i)}}}
{{{-2((x-3)-i)((x-3)+i)}}}
{{{-2((x-3)^2-i^2)}}}
{{{-2((x^2-6x+9)+1)}}}
{{{-2(x-3)^2-1/2)}}}
{{{highlight(y=-2(x-3)^2-1/2)}}}-----standard form
