(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Show that:

(x^2) (2x) (-2)

(2x) (2-x^2) (2x)

(2) (-2x) (-x^2)

= (x^2 + 2)^3

Do not use direct evaluation.

2. Relevant equations

3. The attempt at a solution

As direct evaluation is not permitted, I'm wondering which method should I use? Thank you
