Q. Divide the polynomials. Your answer should be a polynomial.x+3x2+x−6=
Set up division format: Set up the division of the polynomials in long division format.We want to divide x2+x−6 by x+3. We will use polynomial long division to find the quotient.
Divide first term: Divide the first term of the dividend, x2, by the first term of the divisor, x, to get the first term of the quotient.x2 divided by x is x. Write x above the division bar.
Multiply and subtract: Multiply the divisor x+3 by the first term of the quotient x and write the result under the dividend.x×(x+3)=x2+3x. Write this under x2+x.
Bring down next term: Subtract the result from the previous step from the dividend.Subtract x2+3x from x2+x. This gives us −2x−6.
Divide new dividend: Bring down the next term of the dividend, which is −6, to complete the new dividend of −2x−6.Now we have a new dividend of −2x−6.
Multiply and subtract again: Divide the first term of the new dividend, −2x, by the first term of the divisor, x, to get the next term of the quotient.−2x divided by x is −2. Write −2 above the division bar next to x.
Subtract and find remainder: Multiply the divisor x+3 by the new term of the quotient −2 and write the result under the new dividend.−2×(x+3)=−2x−6. Write this under −2x−6.
Write final answer: Subtract the result from the previous step from the new dividend.Subtract −2x−6 from −2x−6. This gives us a remainder of 0.
Write final answer: Subtract the result from the previous step from the new dividend.Subtract −2x−6 from −2x−6. This gives us a remainder of 0.Write the final answer.The quotient is x−2 with a remainder of 0, so the final answer is x−2.
