#"remainder "=-69#

Explanation:

#"suppose when q(x) is divided by "(x-a)#

#"the quotient is g(x) and the remainder is k"#

#"then "q(x)=(x-a)xxg(x)+k#

#"substituting x = a into both sides of this identity"#

#rArrq(a)=0xxg(a)+k#

#rArrq(a)=k#

#"the remainder when q(x) is divided by "(x-a)" is "q(a)#

#rArrq(-2)=8(-2)^3+4(-2)+3=-69#
