instead of putting it in a calculator as (-3p + 6) ^3. Solve it as (-3p + 6) (-3p + 6) (-3p + 6)
Its multiplication so in steps it would look like
(-3p + 6) x (-3p + 6)
= 9p^2 + -18p + -18p + 36
= (9p^2 -36p + 36)
Step 2:
(9p^2 -36p + 36) x (-3p + 6)
= (-27p^3 + 54p^2 + 108p^2 + 216p - 108p + 216)
By factoring completely you need to simplify it by just adding everything up that matches.
(-27p^3 + 162p^2 + 108p + 216)
is the simplified answer
