Q. Divide. If there is a remainder, include it as a simplified fraction.(3x3+11x2+10x)÷(x+2)
Polynomial Long Division: We will use polynomial long division to divide (3x3+11x2+10x) by (x+2). First, we divide the first term of the dividend, 3x3, by the first term of the divisor, x, to get the first term of the quotient. 3x3÷x=3x2
First Term Division: We multiply the divisor (x+2) by the first term of the quotient (3x2) and subtract the result from the dividend.(3x3+11x2+10x)−(3x2⋅(x+2))=(3x3+11x2+10x)−(3x3+6x2)This simplifies to 5x2+10x.
Subtraction and Simplification: Next, we divide the first term of the remaining polynomial, 5x2, by the first term of the divisor, x, to get the next term of the quotient.5x2÷x=5x
Next Term Division: We multiply the divisor (x+2) by the new term of the quotient (5x) and subtract the result from the remaining polynomial.(5x2+10x)−(5x⋅(x+2))=(5x2+10x)−(5x2+10x)This simplifies to 0, so there is no remainder.
