Q. Divide the polynomials.\newlineThe form of your answer should either be p(x) p(x) or p(x)+kx3 p(x)+\frac{k}{x-3} where p(x) p(x) is a polynomial and k k is an integer.\newlinex34x15x3= \frac{x^{3}-4 x-15}{x-3}=\square
  1. Set up long division: Set up the long division.\newlineWe will use polynomial long division to divide (x34x15)(x^3 - 4x - 15) by (x3)(x - 3).
  2. Divide first term of dividend by first term of divisor: Divide the first term of the dividend by the first term of the divisor.\newlineDivide x3x^3 by xx to get x2x^2. Multiply (x3)(x - 3) by x2x^2 and subtract the result from the dividend.\newlinex3x=x2\frac{x^3}{x} = x^2\newline(x3)x2=x33x2(x - 3) \cdot x^2 = x^3 - 3x^2
  3. Write down result and bring down next term: Write down the result and bring down the next term.\newlineAfter subtracting, we bring down the next term of the dividend, which is 4x-4x.\newlineThe new dividend is 3x24x-3x^2 - 4x.
  4. Divide first term of new dividend by first term of divisor: Divide the first term of the new dividend by the first term of the divisor.\newlineDivide 3x2-3x^2 by xx to get 3x-3x. Multiply (x3)(x - 3) by 3x-3x and subtract the result from the new dividend.\newline3x2x=3x\frac{-3x^2}{x} = -3x\newline(x3)3x=3x2+9x(x - 3) \cdot -3x = -3x^2 + 9x
  5. Write down result and bring down next term: Write down the result and bring down the next term.\newlineAfter subtracting, we bring down the next term of the dividend, which is 15-15.\newlineThe new dividend is 9x159x - 15.
  6. Divide first term of new dividend by first term of divisor: Divide the first term of the new dividend by the first term of the divisor.\newlineDivide 9x9x by xx to get 99. Multiply (x3)(x - 3) by 99 and subtract the result from the new dividend.\newline9xx=9\frac{9x}{x} = 9\newline(x3)9=9x27(x - 3) \cdot 9 = 9x - 27
  7. Write down result and find remainder: Write down the result and find the remainder.\newlineAfter subtracting, we find the remainder.\newlineThe new dividend is \(-15 - (27-27) = 1212").\newlineThe remainder is \(12").
  8. Write final answer: Write the final answer.\newlineThe quotient is x23x+9x^2 - 3x + 9 with a remainder of 1212.\newlineThe final answer is in the form p(x)+kx3p(x) + \frac{k}{x - 3}, where p(x)p(x) is the quotient polynomial and kk is the remainder.\newlinep(x)=x23x+9p(x) = x^2 - 3x + 9\newlinek=12k = 12
