Big Ideas: Polynomials are not closed under the operation of division. When dividing polynomials by monomials, we divide one term at a time using the inverse of multiplication and dividing coefficients by coefficients and variables by variables. When dividing bases that are the same, we subtract exponents. Students will build on their knowledge of operations with polynomials. In this task, students learn to divide polynomials by monomials one term at a time while following the rules of exponents and integers. Vocabulary: monomial, remainder, dividend, divisor, quotient
