#color(magenta)((x^3+11x+14) / (x+2) = x^2-2x+15# and remainder of #color(magenta)((-16)/(x+2)#

Explanation:

#color(white)(..........)color(white)(.)ul(x^2-2x+15)#
#x+2|x^3+0+11x+14#
#color(white)(............)ul(x^3+2x^2)#
#color(white)(...............)-2x^2+11x#
#color(white)(................)ul(-2x^2-4x)#
#color(white)(..............................)15x+14#
#color(white)(..............................)ul(15x+30)#
#color(white)(...................................)-16#

#color(magenta)((x^3+11x+14) / (x+2) = x^2-2x+15# and remainder of #color(magenta)((-16)/(x+2)#
