Q. Divide. If there is a remainder, include it as a simplified fraction.(5j3−3j2−2j)÷(j−1)
Divide by First Term: We will use polynomial long division to divide (5j3−3j2−2j) by (j−1). First, we divide the first term of the dividend, 5j3, by the first term of the divisor, j, to get the first term of the quotient. 5j3÷j=5j2
Subtract and Simplify: Now, we multiply the divisor (j−1) by the first term of the quotient (5j2) and subtract the result from the dividend.(5j3−3j2−2j)−(5j2⋅(j−1))=(5j3−3j2−2j)−(5j3−5j2)This simplifies to:−3j2−2j+5j2=2j2−2j
Divide New Dividend: Next, we divide the first term of the new dividend, 2j2, by the first term of the divisor, j, to get the second term of the quotient.2j2÷j=2j
Subtract and Simplify: We multiply the divisor (j−1) by the second term of the quotient (2j) and subtract the result from the new dividend.(2j2−2j)−(2j⋅(j−1))=(2j2−2j)−(2j2−2j)This simplifies to:−2j+2j=0
Final Quotient: Since we have no remainder, the division process is complete. The quotient is the sum of the terms we found: 5j2+2j.
