Q. Divide the polynomials.Your answer should be a polynomial.x+3x2+6x+9=
Recognize division methods: Recognize that the division of polynomials can be performed using polynomial long division or synthetic division. Since the divisor is a binomial of the form (x+a), we can use polynomial long division.
Set up long division: Set up the long division by writing the dividend x2+6x+9 under the long division symbol and the divisor x+3 outside.
Divide first terms: Divide the first term of the dividend (x2) by the first term of the divisor (x) to get the first term of the quotient. This gives us x2/x=x.
Multiply divisor and quotient: Multiply the divisor (x+3) by the first term of the quotient (x) to get x(x+3)=x2+3x.
Subtract to find remainder: Subtract the result of the multiplication from the dividend to find the remainder. We have (x2+6x+9)−(x2+3x)=3x+9.
Bring down next term: Bring down the next term of the dividend if necessary. In this case, we already have the complete remainder 3x+9 to work with.
Divide new remainder: Divide the first term of the new remainder 3x by the first term of the divisor x to get the next term of the quotient. This gives us x3x=3.
Multiply divisor and new quotient: Multiply the divisor (x+3) by the new term of the quotient (3) to get 3(x+3)=3x+9.
Subtract to find new remainder: Subtract the result of the multiplication from the new remainder to find the new remainder. We have (3x+9)−(3x+9)=0.
Determine exact division: Since the remainder is 0, the division is exact, and we have found the quotient. The quotient is the result of the division, which is x+3.
