Question: If \left|x^{2}-6 x+5\right|=0 and |z+3|=z^{2}+2 z-3 then the minimum value of xz is:

a) 2

b) -3

C) 10

d) -15

Approach: We need to understand how to open Absolute value here. The first equation is relatively straightforward. But for the other one, we need to make 2 conditions based on the value of z. Not only that, but we also need to cross-verify whether the final values of z fall in the same category or not.
