Multiply each pair of polynomials: 2x left paren 3x squared + 4x + 5 right paren, and left paren 6x cubed minus 2x + 1 right paren left paren 3x cubed right paren
Use FOIL to multiply each pair: left paren 2x + 3 right paren left paren x + 6 right paren, left paren 3y minus 2 right paren left paren 4y + 2 right paren, and left paren 5z cubed minus 2 right paren left paren 5z cubed plus 2 right paren
Multiply left paren x + 2 right paren left paren 3x square minus 2x + 9 right paren
Multiply left paren x minus 4 right paren left paren x squared + 4x + 16 right paren
Multiply left paren x squared minus 4x + 4 right paren left paren x squared + 4x + 4 right paren
