Q. Divide. If there is a remainder, include it as a simplified fraction.(2c2+5c−7)÷(c−1)
Divide by First Term: We will use polynomial long division to divide (2c2+5c−7) by (c−1). First, we divide the first term of the dividend, 2c2, by the first term of the divisor, c, to get the first term of the quotient. 2c2÷c=2c
Multiply and Subtract: Now, we multiply the divisor c−1 by the first term of the quotient 2c and subtract the result from the dividend.(2c)(c−1)=2c2−2cSubtract this from the dividend:(2c2+5c−7)−(2c2−2c)=5c−2c−7=3c−7
Divide New Term: Next, we divide the new first term of the remaining polynomial, 3c, by the first term of the divisor, c. 3c÷c=3
Multiply and Subtract: We multiply the divisor (c−1) by the new term of the quotient (3) and subtract the result from the remaining polynomial.(3)(c−1)=3c−3Subtract this from the remaining polynomial:(3c−7)−(3c−3)=−7+3=−4
Final Result: Since −4 is a constant and the divisor is a linear term (c−1), we cannot divide further. Therefore, −4 is the remainder.The quotient is 2c+3 with a remainder of −4.
