Hi,

There's a simpler way.

When you don't know where to start, when given , find the modulus, that is and factor it out.

You would then have

Define and

they're both in and are such that

Thus there exists such that and

Hence

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Here, you can find that

So you can divide by 2 on both sides :

Note that and

So your equation is now

That is

Then remember that
