Q. Divide the polynomials.Your answer should be in the form p(x)+x+3k where p is a polynomial and k is an integer.x+3x2+5x+5=
Set up long division: Set up the long division.We will divide the polynomial x2+5x+5 by x+3 using 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).
Multiply and subtract: Multiply the divisor by the term obtained in Step 2 and subtract from the dividend.Multiply x by x+3 to get x2+3x. Subtract this from x2+5x+5 to get the new dividend.(x2+5x+5)−(x2+3x)=2x+5.
Divide new dividend: Divide the new dividend 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).
Multiply and subtract: Multiply the divisor by the term obtained in Step 4 and subtract from the new dividend.Multiply 2 by x+3 to get 2x+6. Subtract this from 2x+5 to get the new remainder.(2x+5)−(2x+6)=−1.
Write final answer: Write the final answer.The quotient polynomial p(x) is x+2 and the remainder is −1. Therefore, the final answer is in the form p(x)+(x+3)k, where p(x)=x+2 and k=−1.
