$x^{2} - 4 x - 12$ $x^2 -4x -12$

Explanation:

Start of by expanding the brackets then simplify

$x^{2} + 2 x - 6 x - 12$ $x^2 +2x -6x -12$

$x^{2} - 4 x - 12$ $x^2 -4x -12$

$x^{2} - 4 x - 12$ $x^2-4x-12$

Explanation:

Given: $(x - 6) (x + 2)$ $color(blue)((x-6))color(green)( (x+2) )$

Multiply everything in the right hand brackets by everything in the left one.

$x (x + 2) ddd - 6 (x + 2) \leftarrow$ $color(green)(color(blue)(x)(x+2) color(white)("ddd") color(blue)(-6)(x+2)) larr$ Notice the minus follows the 6

$color(green)(x^2color(white)(".d")ubrace(+2xcolor(white)("ddd")-6x)-12$

$color(green)(x^2color(white)("dddd")-4xcolor(white)("ddd.")-12)$
