If v and w are different integers, does v=0?

(1) v*w=v^2

(2) w=2

going for A. Requesting OA.

I hate these types of questions to be honest but here's my work steps:

1) V*W=V^2 => this only occurs when V=0, since V and W are different integers based on the 2 min time limit I gave myself. =>Suff.

Answers between A&D now (

Princeton Review Strat)

2) W=2 => doesn't help to solve wherever V=0, insuff.

Since stat 1 is already suff. don't need to go through C. therefore ANS = A

Also requesting someone that actually knows how to do this question to properly dissect it, explain it to dummies like me.

THANX A MILLION!
