Q. Divide the polynomials.Your answer should be a polynomial.x−1x2+2x−3=
Set up long division: Set up the long division.We will divide x2+2x−3 by x−1. This is similar to long division with numbers, but with polynomials.
Divide first term of dividend: 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.
Multiply divisor by first term of quotient: Multiply the divisor by the first term of the quotient.Multiply x−1 by x to get x2−x.
Subtract result from dividend: Subtract the result from the dividend.Subtract x2−x from x2+2x−3 to get 3x−3.
Bring down next term of dividend: Bring down the next term of the dividend.There are no more terms to bring down, so we continue with 3x−3.
Divide first term of new dividend: Divide the first term of 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.
Multiply divisor by new term of quotient: Multiply the divisor by the new term of the quotient.Multiply x−1 by 3 to get 3x−3.
Subtract result from new dividend: Subtract the result from the new dividend.Subtract 3x−3 from 3x−3 to get 0.
Find the quotient: Since the remainder is 0, we have found the quotient.The quotient is x+3.
