6.1.3 Multiplying Polynomials - Practice
2. Multiply.
1. Multiply.
( y 2 − 5 y + 10)( y + 3)
4 x 3 y (3 x 2 − 5 y )
4. The number of items is modeled by h ( x ) = 0.42 x 2 + 0.3 x + 4, and the cost per item is modeled by
3. Multiply.
( p 2 − 5 p + 2)( p 2 − p + 6)
r ( x ) = − 0.005 x 2 − 0.2 x + 7. The total cost is the product of the number of items and the cost per item. Write a polynomial q ( x ) that can be used to model the total cost.
6. Multiply. ( z − 3) 3
5. Expand the expression. (2 m − 3 n ) 3
