Q. Divide the polynomials.Your answer should be a polynomial.x+5x2+10x+25=
Approach for Division: Recognize that the division of polynomials can be approached using polynomial long division or synthetic division. Since the divisor is a binomial of the form x+a, we can use either method. We will use polynomial long division.
Setting up the Long Division: Set up the long division by writing x2+10x+25 under the long division symbol and x+5 outside.
Finding the First Term of the Quotient: Divide the first term of the dividend, x2, by the first term of the divisor, x, to get the first term of the quotient, which is x.Calculation: x2÷x=x
Multiplying and Subtracting: Multiply the divisor x+5 by the first term of the quotient x to subtract from the dividend.Calculation: x⋅(x+5)=x2+5x
Continuing the Division: Subtract the result of the multiplication from the dividend.Calculation: (x2+10x+25)−(x2+5x)=5x+25
Finding the Next Term of the Quotient: Bring down the next term of the dividend, if any, to continue the division. Since there are no more terms to bring down, we continue with 5x+25.
Multiplying and Subtracting Again: Divide the term 5x by the first term of the divisor x to find the next term of the quotient.Calculation: 5x÷x=5
Completing the Division: Multiply the divisor x+5 by the new term of the quotient 5 to subtract from the current dividend.Calculation: 5⋅(x+5)=5x+25
Completing the Division: Multiply the divisor x+5 by the new term of the quotient 5 to subtract from the current dividend.Calculation: 5⋅(x+5)=5x+25Subtract the result of the multiplication from the current dividend.Calculation: (5x+25)−(5x+25)=0
Completing the Division: Multiply the divisor x+5 by the new term of the quotient 5 to subtract from the current dividend.Calculation: 5⋅(x+5)=5x+25Subtract the result of the multiplication from the current dividend.Calculation: (5x+25)−(5x+25)=0Since the remainder is 0, the division is complete, and the quotient is the final answer.
