Q. Divide the polynomials. Your answer should be in the form p(x)+x+5k where p is a polynomial and k is an integer.x+5x2−28=□
Set up division: Set up the division of the polynomials.We are dividing x2−28 by x+5. We will use polynomial long division to find the quotient.
Divide first terms: Divide the first term of the numerator by the first term of the denominator.Divide x2 by x to get x. This will be the first term of the quotient polynomial p(x).
Subtract and multiply: Multiply the divisor by the term found in Step 2 and subtract from the numerator.Multiply x by x+5 to get x2+5x. Subtract this from x2−28 to get −5x−28.
Divide new first term: Divide the new first term of the remainder by the first term of the divisor.Divide −5x by x to get −5. This will be the next term of the quotient polynomial p(x).
Subtract and multiply: Multiply the divisor by the term found in Step 4 and subtract from the current remainder.Multiply −5 by x+5 to get −5x−25. Subtract this from −5x−28 to get −3.
Write final answer: Write the final answer.The quotient polynomial p(x) is x−5, and the remainder is −3. Therefore, the final answer in the form p(x)+x+5k is (x−5)+x+5−3.
