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?
there are no x^2 terms, so no quadratic formula. This was answered already - see the links below.
