The factored form of the equation is (x+4) (x-6) = 0.

Step-by-step explanation:

Because (x-4) (x+2) = x^2-4x+2x-8=16,

so that means x^2-2x-8=16,

move 16 to the other side,

you get x^2-2x-8-16=0,

simplify,

you get x^2-2x-24=0,

which satisfies (x+4) (x-6) = 0 when factored out.

Because (x+4) (x-6) = x^2+4x-6x-24=x^2-2x-24=0.
