The document contains 29 math problems involving polynomial multiplication and division. Students are asked to calculate the products and quotients of polynomials such as (a3 - 3b), (-9x)(-12xy + 5), and (4mn)(5m2n + 6mn2). They are also asked to perform division of polynomials like 18x5 ¡Â 9, (-13p5q3) ¡Â (-13p2q), and (-15ab4 + 3a2b2 - 21b3) ¡Â 3b2. The problems cover a range of operations with monomials and polynomials of varying degrees.
