color(blue)(-11x) " "color(red)(+4)" " color(blue)(+8x)" " color(red)(-4" ") color(blue)(+3x)

$= \textcolor{b l u e}{- 11 x} \text{ " color(blue)(+8x)" " color(blue)(+3x)" "color(red)(-4)" } \textcolor{red}{+ 4}$

$= \textcolor{b l u e}{- 11 x} \textcolor{b l u e}{+ 11 x} + \textcolor{red}{0}$

$= 0$
