Q. Divide. If there is a remainder, include it as a simplified fraction.(5t3+16t2−16t)÷(t+4)______
Set Up Division: First, we set up the division of the polynomial by the binomial in long division format.
Find First Term Quotient: We divide the first term of the polynomial, 5t3, by the first term of the binomial, t, to get the first term of the quotient, which is 5t2.Calculation: 5t3÷t=5t2
Subtract and Multiply: We multiply the entire binomial (t+4) by the term we just found, 5t2, and subtract the result from the polynomial.Calculation: (t+4)(5t2)=5t3+20t2Subtraction: (5t3+16t2−16t)−(5t3+20t2)=−4t2−16t
Find Next Term Quotient: We divide the new leading term, −4t2, by the first term of the binomial, t, to get the next term of the quotient, which is −4t.Calculation: −4t2÷t=−4t
Subtract and Multiply: We multiply the entire binomial (t+4) by the term we just found, −4t, and subtract the result from the remaining polynomial terms.Calculation: (t+4)(−4t)=−4t2−16tSubtraction: (−4t2−16t)−(−4t2−16t)=0
Complete Division: Since the remainder is 0, we have completed the division process.
