( 3y + 2 ) ( 3y + 2 ) = … ? Note :Hmm, masih lama :v
( 3y + 2 )( 3y + 2 )
= 9y² + 6y + 6y + 4
= 9y² + 12y + 4
atauuu
( 3y + 2 ) ( 3y + 2 )
= ( 3y + 2 )²
= (3y)² + (2)(3y)(2) + 2²
= 9y² + 12y + 4
Penjelasan dengan langkah-langkah:
( 3y + 2 ) ( 3y + 2 )
= (3y×3y) + (3y×2) + (2×3y) + (2×2)
= 9y² + 6y + 6y + 4
= 9y² + 12y + 4
