Question

What are the coordinates of the vertex of y = –x2 – 12x – 32?

Answer 1

x^2=12x-32

Explanation:

try to factor by splitting the middle term example x^2-(12*x-32)=0

multiply the coefficient of the first term by the the constant 1 X 32=32

find two factors of 32 whose sum equals the coefficient of the middle term which is answer keys -32 +-1 =-33

-16+-2=-18

-8+4=-12.
