Q. Divide the polynomials. Your answer should be in the form p(x)+kx+4 p(x)+\frac{k}{x+4} where p p is a polynomial and k k is an integer.\newlinex2+1x+4= \frac{x^{2}+1}{x+4}=
  1. Set up division: Set up the division of the polynomials in long division format.\newlineWe will divide the polynomial x2+1x^2 + 1 by x+4x + 4 using polynomial long division.
  2. Determine divisor count: Determine how many times the divisor (x+4)(x + 4) goes into the first term of the dividend x2x^2. The first term of the divisor xx goes into the first term of the dividend x2x^2 exactly xx times because x×x=x2x \times x = x^2.
  3. Multiply and subtract: Multiply the entire divisor (x+4)(x + 4) by the result from Step 22 (x)(x) and subtract it from the dividend (x2+1)(x^2 + 1). Multiplying (x+4)(x + 4) by xx gives us x2+4xx^2 + 4x. We subtract this from x2+1x^2 + 1 to find the remainder. (x2+1)(x2+4x)=4x+1(x^2 + 1) - (x^2 + 4x) = -4x + 1
  4. Bring down next term: Bring down the next term of the dividend, if any, and repeat the process.\newlineSince there are no more terms to bring down, we now have a remainder of 4x+1-4x + 1.
  5. Write result in form: Write the result in the form p(x)+kx+4p(x) + \frac{k}{x + 4} where p(x)p(x) is the quotient and kk is the remainder.\newlineThe quotient from our division is xx and the remainder is 4x+1-4x + 1. However, we need to express the remainder as a constant over the divisor (x+4)(x + 4). To do this, we continue the division process to find the constant term.
  6. Determine remainder division: Determine how many times the divisor (x+4)(x + 4) goes into the remainder (4x+1)(-4x + 1).\newlineThe term 4x-4x cannot be divided by x+4x + 4 to give a polynomial term, so we stop the division here. The remainder is 4x+1-4x + 1.
  7. Express remainder as fraction: Express the remainder as a fraction over the divisor (x+4)(x + 4).\newlineThe remainder is 4x+1-4x + 1, so we write it as (4x+1)/(x+4)(-4x + 1)/(x + 4).
  8. Final answer: Since we cannot simplify the remainder further, we have our final answer.\newlineThe final answer is p(x)+kx+4p(x) + \frac{k}{x + 4} where p(x)=xp(x) = x and k=4x+1k = -4x + 1.
