When you are making perfect squares,

the easy way is just to take HALF of the value of the middle term,

and then square it.

Half of -12 is -6.

-6 squared is 36.

The expression should then be:

And if we continue, then we can see that this can be factored as:

or even more simply written as

which is WHY we do this. :)

Of course, this only works when the coefficient for the term is 1, so be careful when trying this with trickier expressions.

There's a LOT more to it, but this is the basic info you need to answer the question.

I hope this helps! :)
