Simplifying polynomial expressions

Question

1.    3(18z-4w)+2(10z-6w)

 

2.    10q(16x+11)

 

thank you!! 

Answer 1

1)

 

We distribute the terms to get rid of any parentheses.  Then combine like terms.

 

54z - 12w + 20z - 12w =

 

-24w + 74z

 

 

2)

 

Distribute to get rid of parentheses.

 

160xq + 110q

 

 

Since we cannot combine like terms here, we leave it as it is.
