#(x+4)(x+1)#

Explanation:

Assuming we're being asked to factor, we need to find two numbers that have a product of #4# and sum up to #5#. The product is positive, so the signs are the same.

After some trial and error, we arrive at #4# and #1#. Thus, #x^2+5x+4# can be alternatively written as

#(x+4)(x+1)#

Hope this helps!
