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!

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
