x^2+5x+6=0
What I do when factoring.  I look at the third term and see what factors can comprise it.
Hmmmmmmm seems as though Griff has solved it.

Then I should continue with my explanation?

yes please. :)

x^2+5x+6=0
Look for the factors of 6
2 & 3
and 6 & 1
Then I look at the second term 5x
and it seems the 2 and the three multiplied equal 6  and
2 + 3 = 5 
So, this was an easily factorable equation.

Thankyou!!!

I just thought I'd mention that whenever I factor an equation, I always make sure that the factor of the x² term is always 1.  It makes life much simpler.
So if you have 3x² + 6x +12 =0
I'd divide it all by 3
x² + 2x + 4 = 0
