(3y−40)
Rewrite ( 3y − 4 ) 2 ( 3y - 4 ) 2 as ( 3y − 4 ) ( 3y − 4 ) ( 3y - 4 ) ( 3y - 4 ) .
( 3y − 4 ) ( 3y − 4 ) ( 3y - 4 ) ( 3y - 4 )
Expand ( 3y − 4 ) ( 3y − 4 ) ( 3y - 4 ) ( 3y - 4 ) using the FOIL Method.
3y (3y) + 3y ⋅ − 4 − 4 ( 3y ) − 4 ⋅ − 43y ( 3y ) + 3y ⋅ - 4 - 4 ( 3y ) - 4 ⋅ -
Simplify and combine like terms.
Simplify each term. 9y 2 − 12y − 12y + 16 9 y 2 - 12 y - 12 y + 16
Subtract 12y 12y from − 12y - 12y . 9y2 − 24y + 16
So 3-4[9-(3y-4)] simplfied is (3y−40).
