Q. Divide the polynomials.\newlineThe form of your answer should either be p(x) p(x) or p(x)+kx+1 p(x)+\frac{k}{x+1} where p(x) p(x) is a polynomial and k k is an integer.\newline3x3+x11x+1= \frac{3 x^{3}+x-11}{x+1}=\square
  1. Set up long division: Set up the long division.\newlineWe will use polynomial long division to divide (3x3+x11)(3x^3 + x - 11) by (x+1)(x + 1).
  2. Divide first term: Divide the first term of the dividend by the first term of the divisor.\newlineDivide 3x33x^3 by xx to get 3x23x^2. Write this term above the division bar.
  3. Multiply divisor by term: Multiply the divisor by the term found in Step 22.\newlineMultiply (x+1)(x + 1) by 3x23x^2 to get 3x3+3x23x^3 + 3x^2. Write this below the dividend.
  4. Subtract result: Subtract the result of Step 33 from the dividend.\newlineSubtract (3x3+3x2)(3x^3 + 3x^2) from (3x3+x11)(3x^3 + x - 11) to get 3x2+x11-3x^2 + x - 11.
  5. Bring down next term: Bring down the next term of the dividend.\newlineSince there is no x2x^2 term in the original dividend, we consider it as 0x20x^2. So, we bring down the xx term to get 3x2+x-3x^2 + x.
  6. Repeat division process: Repeat the division process with the new polynomial.\newlineDivide 3x2-3x^2 by xx to get 3x-3x. Write this term above the division bar next to 3x23x^2.
  7. Multiply divisor by term: Multiply the divisor by the term found in Step 66.\newlineMultiply (x+1)(x + 1) by 3x-3x to get 3x23x-3x^2 - 3x. Write this below the current dividend.
  8. Subtract result: Subtract the result of Step 77 from the current dividend.\newlineSubtract (3x23x)(-3x^2 - 3x) from (3x2+x)(-3x^2 + x) to get 4x114x - 11.
  9. Bring down next term: Bring down the next term of the dividend.\newlineSince there is no constant term in the current dividend, we bring down the 11-11 to get 4x114x - 11.
  10. Repeat division process: Repeat the division process with the new polynomial.\newlineDivide 4x4x by xx to get 44. Write this term above the division bar next to 3x-3x.
  11. Multiply divisor by term: Multiply the divisor by the term found in Step 1010.\newlineMultiply (x+1)(x + 1) by 44 to get 4x+44x + 4. Write this below the current dividend.
  12. Subtract result: Subtract the result of Step 1111 from the current dividend.\newlineSubtract (4x+4)(4x + 4) from (4x11)(4x - 11) to get 15-15.
  13. Write final answer: Write the final answer.\newlineThe quotient is 3x23x+43x^2 - 3x + 4 with a remainder of 15-15. The remainder is written as a fraction with the divisor (x+1)(x + 1).\newlineThe final answer is 3x23x+415x+13x^2 - 3x + 4 - \frac{15}{x + 1}.
