Q. Divide the polynomials. Your answer should be in the form p(x)+x−2k where p is a polynomial and k is an integer.x−2x2−3x+9=
Set up long division: Set up the long division.We will divide the polynomial x2−3x+9 by x−2 using long division.
Divide first term: Divide the first term of the dividend by the first term of the divisor. 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 term obtained in Step 2.Multiply (x−2) by x to get x2−2x.
Subtract result: Subtract the result of Step 3 from the dividend.Subtract x2−2x from x2−3x+9 to get −x+9.
Bring down next term: Bring down the next term of the dividend.Since there are no more terms to bring down, we proceed to the next step.
Divide new term: Divide the new term of the dividend by the first term of the divisor. Divide −x by x to get −1. This will be the next term of the quotient polynomial p(x).
Multiply divisor again: Multiply the divisor by the term obtained in Step ext{ extdollar}6 ext{ extdollar}.Multiply ext{ extdollar}(x - 2) ext{ extdollar} by ext{ extdollar}−1 ext{ extdollar} to get ext{ extdollar}-x + 2 ext{ extdollar}.
Subtract result again: Subtract the result of Step 7 from the new dividend.Subtract (−x+2) from −x+9 to get 7.
Check remainder: Since the degree of the remainder (7) is less than the degree of the divisor (x−2), we cannot continue the division.The remainder is 7, and the quotient polynomial p(x) is x−1.
Write final answer: Write the final answer in the form p(x)+x−2k. The quotient polynomial p(x) is x−1, and the remainder is 7, so the final answer is x−1+x−27.
