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+7x+12=
Set up division: Set up the division of the polynomials.We will use polynomial long division to divide x2+7x+12 by x+2.
Divide first term: 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 polynomial part of the answer.
Multiply divisor: Multiply the divisor by the term found in Step 2.Multiply x by x+2 to get x2+2x.
Subtract result: Subtract the result of Step 3 from the original numerator.Subtract (x2+2x) from (x2+7x+12) to get 5x+12.
Divide new 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 polynomial part of the answer.
Multiply divisor: Multiply the divisor by the term found in Step 5.Multiply 5 by x+2 to get 5x+10.
Subtract result: Subtract the result of Step 6 from the remainder found in Step 4.Subtract (5x+10) from (5x+12) to get 2.
Write final answer: Write the final answer.The polynomial part of the answer is x+5, and the remainder is 2. The remainder is written as a fraction over the original divisor.The final answer is p(x)+(x+2)k, where p(x)=x+5 and k=2.
