Answer 1

Solutions

1) Distribute

3a×8a+3a×−8

2) Gather like terms

3×8a×a+3a×−8

3) Simplify 3×8a×a to 24a²

24a²+3a×−8

4) Simplify 3a×−8 to −3a×8

24a²+−3a×8

5) Simplify 3a×8 to 24a

24a²−24a

Answer 2

3 a ( 8a - 8 ) :

Distributive parentheses using: a ( b + c ) = ab + ac

Apply minus - plus rules

+(-a) = -a

= 3a * 8 a - 3 a * 8


= 24 a² - 24 a

hope this helps!
