How do you divide #(8g^3-6g^2+3g+5)/(2g+3)#?

By the ordinary algorithm division or by Ruffini method as the divisor is of first degree
#Q(x)=4g^2-9g+15# and #R(x)=-40#

Explanation:

I prefer the ordinary algorithm division because it is of "universal use"
#8g^3-6g^2+3g+5-(2g+3)( **4g^2** )=-18g^2+3g+5# first partial quotient and remainder

#-18g^2+3g+5-(2g+3)( **-9g** )=30g+5# second partial quotient and remainder

#30g+5-(2g+3)( **15** )=-40# last quotient term and final remainder

the quotient is #Q(x)=4g^2-9g+15 # the remainder is # R(x)= -40 #
