The correct answer for the question that is being presented above is this one: "D. b² − 3b + 18 R252. The quotient of b^3+4b^2-3b+126/b+7. In order to get the answer, you have to start dividing b^3 by b. Then multiply the quotient to b + 7. Then after that, subtract. Do the same thing until you reached the end.
