#(x+12)(x+1)#

#"the factors of + 12 which sum to + 13 are + 12 and + 1"#

#x^2+13x+12=(x+12)(x+1)#

#(x+12)(x+1)#

We need to think of two numbers that sum up to #13# and have a product of #12#. These will become our factors.

After some trial and error, we arrive at #12# and #1#. Thus, we have

#(x+12)(x+1)#

Hope this helps!
