#d-2+2/(d-3)#

Explanation:

#"one way is to use the divisor as a factor in the numerator"#

#"consider the numerator"#

#color(red)(d)(d-3)color(magenta)(+3d)-5d+8#

#=color(red)(d)(d-3)color(red)(-2)(d-3)color(magenta)(-6)+8#

#=color(red)(d)(d-3)color(red)(-2)(d-3)+2#

#"quotient "=color(red)(d-2)," remainder "=2#

#rArr(d^2-5d+8)/(d-3)=d-2+2/(d-3)#
