Q. Divide the polynomials. Your answer should be in the form p(x)+x+1k where p is a polynomial and k is an integer.x+1x2−2x−8=
Set up division: Set up the division of the polynomials.We are dividing the polynomial x2−2x−8 by x+1. We will use polynomial long division to find the quotient and the remainder.
Divide first term: Divide the first term of the numerator by the first term of the denominator. Divide x2 by x to get x. This will be the first term of the quotient polynomial p(x).
Multiply divisor: Multiply the divisor by the first term of the quotient.Multiply x by x+1 to get x2+x. This will be subtracted from the numerator.
Subtract result: Subtract the result from the numerator.Subtract x2+x from x2−2x−8 to get −3x−8.
Bring down next term: Bring down the next term of the numerator. Since there are no more terms to bring down, we proceed to the next step.
Divide new term: Divide the new term of the numerator by the first term of the denominator.Divide −3x by x to get −3. This will be the next term of the quotient polynomial p(x).
Multiply divisor: Multiply the divisor by the new term of the quotient. Multiply −3 by x+1 to get −3x−3. This will be subtracted from the current numerator.
Subtract result: Subtract the result from the current numerator.Subtract (−3x−3) from −3x−8 to get −5. This is the remainder of the division.
Write final answer: Write the final answer.The quotient polynomial p(x) is x−3, and the remainder is −5. Therefore, the final answer in the form p(x)+x+1k is (x−3)+x+1−5.
