( 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
