Data Sufficiency (DS) | If x is positive, is x > 3 ? (1) (x - 1)^2 > 4 (2) (x - 2)^2 > 9

Hi Bunuel,

Apologies for the follow-up question and the back and forth. I read the explanation in the links in your original post, but I'm still not 100% tracking. If the inequality is (x-3) (x+1) > 0, why is that any different than when the equation is = 0? I don't understand the reasoning behind changing the ">" sign for the root -1.

Thank you
