$(x+3)(x+1)$

$x^2+4x+3$ is in the general form $x^2+bx+c$

which can also be written as
$x^2+("sum of roots")x+("product of roots")$

which basically means that you need to find TWO roots that when added together equal to 4 and when multiplied together equal to 3.

So the numbers that make the above statement true are
$x=1 and x=3$

$x²+4x+3=(x+1)(x+3)$

$x²+4x+3=x²+3x+x+3$
$=x(x+3)+x+3$
$=(x+1)(x+3)$
