Q. Divide. If there is a remainder, include it as a simplified fraction.(4n3+22n2−12n)÷(n+6)______
Divide by First Term: We will use polynomial long division to divide (4n3+22n2−12n) by (n+6). First, we divide the first term of the dividend, 4n3, by the first term of the divisor, n, to get the first term of the quotient. 4n3÷n=4n2
Subtract and Simplify: We multiply the divisor (n+6) by the first term of the quotient (4n2) and subtract the result from the dividend.(4n3+22n2−12n)−(4n2×(n+6))=(4n3+22n2−12n)−(4n3+24n2)This simplifies to −2n2−12n.
Divide New Leading Term: Next, we divide the new leading term of the remaining polynomial, −2n2, by the first term of the divisor, n. −2n2÷n=−2n
Subtract and Simplify: We multiply the divisor (n+6) by the new term of the quotient (−2n) and subtract the result from the remaining polynomial.(−2n2−12n)−(−2n×(n+6))=(−2n2−12n)−(−2n2−12n)(This simplifies to \$0\), meaning there is no remainder.
Final Quotient: The quotient we have found is \(4n^2 - 2n\), and there is no remainder.\(\newline\)Therefore, the division is complete.
