Answer 1

What we have here is an expression, not an equation.  Equations have equal signs associated with them.

 

 

First, we simplify the part in the {} using distributive property.  Then we work our way down.

 

7(4a - 3) - 3a{8 - 2a - 4a²}

 

 

Distribute again to get rid of the parentheses and brackets.

 

28a - 21 - 24a + 6a² + 12a³

 

 

Combine any like terms. Write the expression in descending order.

 

12a³+ 6a² + 4a - 21
