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+4=
Set up division: Set up the division of the polynomials using long division.We are dividing x2+4 by x−3. We will use polynomial long division to find the quotient and the remainder.
Divide first terms: 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).
Subtract and find new dividend: Multiply the divisor by the term found in Step 2 and subtract from the dividend.Multiply (x−3) by x to get x2−3x. Subtract this from x2+4 to find the new dividend.(x2+4)−(x2−3x)=3x+4.
Divide new dividend: Divide the new dividend by the first term of the divisor.Divide 3x by x to get 3. This will be the next term of the quotient polynomial p(x).
Subtract and find remainder: Multiply the divisor by the term found in Step 4 and subtract from the new dividend.Multiply (x−3) by 3 to get 3x−9. Subtract this from 3x+4 to find the remainder.(3x+4)−(3x−9)=13.
Write final answer: Write the final answer.The quotient polynomial p(x) is x+3 and the remainder is 13. Therefore, the final answer in the form p(x)+x−3k is:x+3+x−313.
