$(x + 2) (x + 10)$ $(x+2)(x+10)$

Explanation:

$x^{2} + 12 x + 20$ $x^2+12x+20$
first of all we'll devide the midddle term in two parts such that their sum =12x and their product = $20 x^{2}$ $20x^2$

$x^{2} + 10 x + 2 x + 20$ $x^2+10x+2x+20$

$x (x + 10) + 2 (x + 10$ $x(x+10)+2(x+10$

$(x + 2) (x + 10)$ $(x+2)(x+10)$
