Question

multiply the following : ​

Answer 1

Answer:

c) 4p²q - 6pq

f) -3x²yz - 9xy²z

c) 4p² - 9pq + 2q²

f) 6p + 6z - 7pz - 7z²

c) 64pq + 24q² - 40xq

Step-by-step explanation:

c) (2p - 3q) * 2pq       = 4p²q - 6pq²

f)  (-3x - 9y) * xyz        = -3x²yz - 9xy²z

c) (4p - q) * (p - 2q)     = 4p² - 8pq - pq + 2q² =  4p² - 9pq + 2q²

f)  (6 - 7z) * (p + z)       = 6p + 6z - 7pz - 7z²

c) (8p + 3q - 5 x) * 8q = 64pq + 24q² - 40xq
