Answer 15

oh... alrighty(: But how does the x variable just disappear...?

Answer 16

See the -24?
It never went away.
-24 couldn't sacrifice an x (because it didn't have one!)

Answer 17

If you choose the second one, you need to distribute that extra x
...and you'll get this:
-6x^3 + 18x^2 - 24x
not
-6x^2 + 18x - 24
