Q. Divide the polynomials. Your answer should be in the form p(x)+x−2k where p is a polynomial and k is an integer.x−2x2−5=
Set up division: Set up the division of the polynomials in long division format.We will divide (x2−5) by (x−2) using polynomial long division.
Divide first term: Divide the first term of the dividend by the first term of the divisor.Divide x2 by x to get x. This will be the first term of the quotient polynomial p(x).Calculation: x2/x=x
Multiply and subtract: Multiply the divisor by the result from Step 2 and subtract from the dividend.Multiply (x−2) by x to get (x2−2x). Subtract this from (x2−5).Calculation: (x2−5)−(x2−2x)=2x−5
Bring down next term: Bring down the next term of the dividend, if any.Since there are no more terms to bring down, we proceed to the next step.
Divide result: Divide the result from Step 3 by the first term of the divisor.Divide 2x by x to get 2. This will be the next term of the quotient polynomial p(x).Calculation: 2x/x=2
Multiply and subtract: Multiply the divisor by the result from Step 5 and subtract from the result of Step 3.Multiply (x−2) by 2 to get (2x−4). Subtract this from (2x−5).Calculation: (2x−5)−(2x−4)=−1
Check for completion: Since the degree of the remainder (−1) is less than the degree of the divisor (x−2), we cannot continue the division.The remainder is −1, and this will be the value of k in the final answer.
Write final answer: Write the final answer in the form p(x)+x−2k.The quotient polynomial p(x) is x+2, and the remainder is −1.Final Answer: p(x)=x+2, k=−1
