Q. Divide. If there is a remainder, include it as a simplified fraction.(5b2+3b−2)÷(b+1)______
Polynomial Long Division: We will use polynomial long division to divide (5b2+3b−2) by (b+1). First, we divide the first term of the dividend, 5b2, by the first term of the divisor, b, to get the first term of the quotient. 5b2÷b=5b
First Term Division: Now, we multiply the entire divisor (b+1) by the first term of the quotient (5b) and subtract the result from the original polynomial.(5b)(b+1)=5b2+5bSubtract this from the original polynomial:(5b2+3b−2)−(5b2+5b)=−2b−2
Subtraction and Multiplication: Next, we divide the new first term of the remaining polynomial, −2b, by the first term of the divisor, b. −2b÷b=−2
New Term Division: We multiply the entire divisor (b+1) by the new term of the quotient (−2) and subtract the result from the remaining polynomial.(−2)(b+1)=−2b−2Subtract this from the remaining polynomial:(−2b−2)−(−2b−2)=0
Final Quotient: Since the remainder is 0, we have no remainder and the division is exact.The quotient is the sum of the terms we found: 5b−2.
