so with this one i do the same thing multiplying what inside absolute value bracket bar with what outside?

|2x-8|-2 = 4x
so that start me off as -4x+16 = 4x or 4x-16 = 4x.

solve equation |x^2-2x-6| = 4
this nothing to do with factoring right? i just add six to both sides and add 2x to both sides?

it actually say to use quadratic formula so i subtract 4 from both sides to get an equation by itself so i plug it in?
