Let's perform a synthetic division
#color(white)(aaaa)##2##color(white)(aaaaaa)##|##color(white)(aa)##1##color(white)(aaaaaa)##0##color(white)(aaaa)##-1##color(white)(aaaa)##5##color(white)(aaa)##-10##color(white)(aaa)##-75#
#color(white)(aaaaaaaaaaaa)#____________
#color(white)(aaaa)##color(white)(aaaaaaa)##|##color(white)(aaaa)##color(white)(aaaaa)##2##color(white)(aaaaa)##4##color(white)(aaaaa)##6##color(white)(aaaa)##22##color(white)(aaaaa)##24#
#color(white)(aaaaaaaaaaaa)#______________
#color(white)(aaaa)##color(white)(aaaaaaa)##|##color(white)(aaa)##1##color(white)(aaaaa)##2##color(white)(aaaaa)##3##color(white)(aaaaa)##11##color(white)(aaa)##12##color(white)(aaaa)##color(red)(-41)#
The remainder is #color(red)(-51)# and the quotient is #=x^4+2x^3+3x^2+11x+12#
Therefore,
#(x^5-x^3+5x^2-10x-75)/(x-2)#
#=x^4+2x^3+3x^2+11x+12-11/(x-2)#
