ok let me show the general idea then we can do this specific problem

starting with a quadratic
$$x^2 + bx + c$$
it can be factored to look like this
$$(x +p)(x+q)$$
only  if
$$p + q = b$$
and
$$p*q = c$$

So the goal is always to find 2 numbers which multiply to get "c" and add to get "b"

dumbcow · Answer

now think of 2 numbers that multiply together to get 11
