Q. Divide the polynomials.The form of your answer should either be p(x) or p(x)+x+1k where p(x) is a polynomial and k is an integer.x+13x3+x−11=□
Set up long division: Set up the long division.We will use polynomial long division to divide (3x3+x−11) by (x+1).
Divide first term: Divide the first term of the dividend by the first term of the divisor.Divide 3x3 by x to get 3x2. Write this term above the division bar.
Multiply divisor by term: Multiply the divisor by the term found in Step 2.Multiply (x+1) by 3x2 to get 3x3+3x2. Write this below the dividend.
Subtract result: Subtract the result of Step 3 from the dividend.Subtract (3x3+3x2) from (3x3+x−11) to get −3x2+x−11.
Bring down next term: Bring down the next term of the dividend.Since there is no x2 term in the original dividend, we consider it as 0x2. So, we bring down the x term to get −3x2+x.
Repeat division process: Repeat the division process with the new polynomial.Divide −3x2 by x to get −3x. Write this term above the division bar next to 3x2.
Multiply divisor by term: Multiply the divisor by the term found in Step 6.Multiply (x+1) by −3x to get −3x2−3x. Write this below the current dividend.
Subtract result: Subtract the result of Step 7 from the current dividend.Subtract (−3x2−3x) from (−3x2+x) to get 4x−11.
Bring down next term: Bring down the next term of the dividend.Since there is no constant term in the current dividend, we bring down the −11 to get 4x−11.
Repeat division process: Repeat the division process with the new polynomial.Divide 4x by x to get 4. Write this term above the division bar next to −3x.
Multiply divisor by term: Multiply the divisor by the term found in Step 10.Multiply (x+1) by 4 to get 4x+4. Write this below the current dividend.
Subtract result: Subtract the result of Step 11 from the current dividend.Subtract (4x+4) from (4x−11) to get −15.
Write final answer: Write the final answer.The quotient is 3x2−3x+4 with a remainder of −15. The remainder is written as a fraction with the divisor (x+1).The final answer is 3x2−3x+4−x+115.
