A standard multiplication you should know is %28a%2Bb%29%28a-b%29+=+a%5E2+-+b%5E2 where each of a and b can be any number, variable or other expression (You can FOIL it, but it would be good to learn this formula).
 
In this case, a = x, b = 12, so %28x%2B12%29%28x-12%29=x%5E2+-+12%5E2=x%5E2+-+144.
