Q. Divide the polynomials.\newlineThe form of your answer should either be p(x) p(x) or p(x)+kx+3 p(x)+\frac{k}{x+3} where p(x) p(x) is a polynomial and k k is an integer.\newline2x3x212x+3= \frac{2 x^{3}-x^{2}-12}{x+3}=
  1. Set up long division: Set up the long division.\newlineWe will use polynomial long division to divide (2x3x212)(2x^3 - x^2 - 12) by (x+3)(x + 3).
  2. Divide first term: Divide the first term of the dividend by the first term of the divisor.\newlineDivide 2x32x^3 by xx to get 2x22x^2.\newlineWrite 2x22x^2 above the division bar.
  3. Multiply divisor and result: Multiply the divisor (x+3)(x + 3) by the result from Step 22 (2x2)(2x^2).\newline2x2(x+3)=2x3+6x22x^2 * (x + 3) = 2x^3 + 6x^2.
  4. Subtract result from dividend: Subtract the result from Step 33 from the dividend.\newline(2x3x212)(2x3+6x2)=7x212(2x^3 - x^2 - 12) - (2x^3 + 6x^2) = -7x^2 - 12.\newlineBring down the next term if necessary.
  5. Divide new dividend: Divide the first term of the new dividend (7x2-7x^2) by the first term of the divisor (xx).\newlineDivide 7x2-7x^2 by xx to get 7x-7x.\newlineWrite 7x-7x above the division bar next to 2x22x^2.
  6. Multiply divisor and result: Multiply the divisor (x+3)(x + 3) by the result from Step 55 (7x)(-7x).\newline7x×(x+3)=7x221x-7x \times (x + 3) = -7x^2 - 21x.
  7. Subtract result from new dividend: Subtract the result from Step 66 from the new dividend.\newline(7x212)(7x221x)=21x12(-7x^2 - 12) - (-7x^2 - 21x) = 21x - 12.
  8. Divide new dividend: Divide the first term of the new dividend (21x21x) by the first term of the divisor (xx).\newlineDivide 21x21x by xx to get 2121.\newlineWrite 2121 above the division bar next to 2x27x2x^2 - 7x.
  9. Multiply divisor and result: Multiply the divisor (x+3)(x + 3) by the result from Step 88 (21)(21).\newline21×(x+3)=21x+6321 \times (x + 3) = 21x + 63.
  10. Subtract result from new dividend: Subtract the result from Step 99 from the new dividend.\newline(21x12)(21x+63)=75(21x - 12) - (21x + 63) = -75.
  11. Write the remainder: Write the remainder.\newlineSince 75-75 cannot be divided by x+3x + 3, we write it as the remainder in the form of (75)/(x+3)(-75)/(x + 3).
  12. Combine quotient and remainder: Combine the quotient and the remainder to express the final answer.\newlineThe quotient is 2x27x+212x^2 - 7x + 21 and the remainder is 75x+3\frac{-75}{x + 3}.\newlineThe final answer is p(x)+kx+3p(x) + \frac{k}{x + 3}, where p(x)=2x27x+21p(x) = 2x^2 - 7x + 21 and k=75k = -75.
