Q. Divide. If there is a remainder, include it as a simplified fraction.(3c3−6c2−9c)÷(c−3)
Use polynomial long division: To divide the polynomial (3c3−6c2−9c) by the binomial (c−3), we will use polynomial long division.
Find first term of quotient: First, we divide the leading term of the polynomial, 3c3, by the leading term of the binomial, c, to get the first term of the quotient, which is 3c2.Calculation: (3c3)÷(c)=3c2
Subtract and continue division: Next, we multiply the entire binomial (c−3) by the term we just found, 3c2, and subtract the result from the original polynomial.Calculation: (c−3)×3c2=3c3−9c2Subtraction: (3c3−6c2−9c)−(3c3−9c2)=3c2−9c
Find next term of quotient: Now, we divide the leading term of the new polynomial, 3c2, by the leading term of the binomial, c, to get the next term of the quotient, which is 3c.Calculation: (3c2)÷(c)=3c
Subtract and continue division: We multiply the entire binomial (c−3) by the term we just found, 3c, and subtract the result from the new polynomial.Calculation: (c−3)×3c=3c2−9cSubtraction: (3c2−9c)−(3c2−9c)=0
Complete division and find quotient: Since we have no remainder, the division is complete. The quotient is the sum of the terms we found: 3c2+3c.
