Q. Divide. If there is a remainder, include it as a simplified fraction.(y3+7y2+10y)÷(y+5)______
Divide leading terms: We will use polynomial long division to divide (y3+7y2+10y) by (y+5). First, we divide the leading term of the numerator, y3, by the leading term of the denominator, y, to get the first term of the quotient. y3÷y=y2
Multiply and subtract: Now, we multiply the entire divisor (y+5) by the first term of the quotient (y2) and subtract the result from the original polynomial.(y+5)(y2)=y3+5y2(y3+7y2+10y)−(y3+5y2)=2y2+10y
Divide new polynomial: Next, we divide the leading term of the new polynomial 2y2 by the leading term of the divisor y to get the next term of the quotient.y2y2=2y
Multiply and subtract: We multiply the entire divisor (y+5) by the new term of the quotient (2y) and subtract the result from the new polynomial.(y+5)(2y)=2y2+10y(2y2+10y)−(2y2+10y)=0
Division complete: Since we have no remainder, the division is complete. The quotient is the sum of the terms we found: y2+2y.
