Q. Divide the polynomials.\newlineThe form of your answer should either be p(x) p(x) or p(x)+kx+2 p(x)+\frac{k}{x+2} where p(x) p(x) is a polynomial and k k is an integer.\newline3x3+x24x+12x+2= \frac{3 x^{3}+x^{2}-4 x+12}{x+2}=
  1. Set up division: Set up the long division.\newlineWe will use polynomial long division to divide 3x3+x24x+123x^3 + x^2 - 4x + 12 by x+2x + 2.
  2. Divide first term: Divide the first term of the numerator by the first term of the denominator.\newlineDivide 3x33x^3 by xx to get 3x23x^2.\newlineWrite 3x23x^2 above the division bar.
  3. Multiply divisor: Multiply the entire divisor by the result from Step 22.\newlineMultiply (x+2)(x + 2) by 3x23x^2 to get 3x3+6x23x^3 + 6x^2.
  4. Subtract result: Subtract the result from Step 33 from the corresponding terms of the dividend.\newlineSubtract (3x3+6x2)(3x^3 + 6x^2) from (3x3+x2)(3x^3 + x^2) to get 5x2-5x^2.\newlineBring down the next term of the dividend, which is 4x-4x, to get 5x24x-5x^2 - 4x.
  5. Divide new leading term: Divide the new leading term of the remainder by the first term of the divisor.\newlineDivide 5x2-5x^2 by xx to get 5x-5x.\newlineWrite 5x-5x above the division bar next to 3x23x^2.
  6. Multiply divisor again: Multiply the entire divisor by the result from Step 55.\newlineMultiply (x+2)(x + 2) by 5x-5x to get 5x210x-5x^2 - 10x.
  7. Subtract result again: Subtract the result from Step 66 from the corresponding terms of the current remainder.\newlineSubtract (5x210x)(-5x^2 - 10x) from (5x24x)(-5x^2 - 4x) to get 6x6x.\newlineBring down the next term of the dividend, which is +12+12, to get 6x+126x + 12.
  8. Bring down next term: Divide the new leading term of the remainder by the first term of the divisor.\newlineDivide 6x6x by xx to get 66.\newlineWrite 66 above the division bar next to 3x25x3x^2 - 5x.
  9. Divide new leading term again: Multiply the entire divisor by the result from Step 88.\newlineMultiply (x+2)(x + 2) by 66 to get 6x+126x + 12.
  10. Multiply divisor again: Subtract the result from Step 99 from the corresponding terms of the current remainder.\newlineSubtract (6x+12)(6x + 12) from (6x+12)(6x + 12) to get 00.
  11. Subtract result again: Write the final answer.\newlineSince there is no remainder, the final answer is just the quotient we have found.\newlineThe quotient is 3x25x+63x^2 - 5x + 6.
