Q. The form of your answer should either be p(x) or p(x)+x−3k where p(x) is a polynomial and k is an integer. x−44x3−14x2−7x−4
Identify Problem Type: Identify the type of problem and the method to solve it. We need to simplify the rational expression by performing polynomial long division.
Set Up Division: Set up the division of (4x3−14x2−7x−4) by (x−4). Start dividing the highest degree terms: Divide 4x3 by x to get 4x2.
Multiply and Subtract: Multiply 4x2 by (x−4) and subtract from the original polynomial.4x2×(x−4)=4x3−16x2(4x3−14x2−7x−4)−(4x3−16x2)=2x2−7x−4
Divide New Term: Divide the new term 2x2 by x to get 2x. Multiply 2x by (x−4) and subtract from the current polynomial. 2x∗(x−4)=2x2−8x(2x2−7x−4)−(2x2−8x)=x−4
Divide x: Divide x by x to get 1.Multiply 1 by (x−4) and subtract from the current polynomial.1×(x−4)=x−4(x−4)−(x−4)=0
