The answer would be D because it is comparing cats and dogs in the shelter. I assume you made a typo saying neiborhood instead of shelter. Hope this helps you
Okay, so first you set equal to 0:

Next simplify the equation so that the leading coefficient is positive:

Looking at the quadratic equation you can't easily simplify it, so plug it into the quadratic equation and simplify:

I noticed a couple mistakes in your work, so if you want me to I can explain them in the comments section :)
Step-by-step explanation:
px^2-qx+r
p(x^2-q/px)+r
p[(x^2-q/px +(q/2p)^2_(q/2p)^2)]+r
p[(x-q/2p)^2 -q^2/4p^2)]+r
p(x-q/2p)^2 -q^/4p+r
p(x-q/2p)^2-(q^2-4pr)/4p
