To divide a polynomial by a monomial, we will need to use the quotient rule for exponents, the zero exponent rule, and the negative exponent rule.

Chapter 5-6 Dividing Polynomials To divide a polynomial by a polynomial, use the same method as when performing long division. dividend divisor 1. Divide 6t 2 by 2t. Write the quotient above the term containing the t. 3t3t 2. Multiply the 3t by 2t + 5. Write the product under the like terms. 6t 2 + 15t 3. Subtract. Bring down the remaining term. -16t - 40
