How exactly do I do this?
I'm supposed to solve for x by completing the square (Grade 11 math).

I'm just confused on this whole completing squares method. I've been at this one for a couple of hours. Help!

${1\over{x^3+2}}-{1\over{x^3+3}}={1\over12}$

I would do this...

Substitute: $m = x^{3}$

Solve for m.

Then worry about solving for x.

Wow, you came back!

On second thought, it might be even more fun to substitute $m = x^{3} + 2$ and see what happens.
