= a² + 2ab + b²

materi : Aljabar

jenjang : SMP

Kelas : 7

⏩ Penyelesaian soal:

Diketahui:

  • ( a + b )²

Ditanya:

  • Dijabarkan

Jawab:

= ( a + b )²

= ( a + b ) ( a + b )

= ( a × a ) + ( b × a ) + ( a × b ) + ( b × b )

= a² + ( b × a ) + ( a × b ) + b²

= + 2ab +

Kesimpulan

Jadi, jabaran dari ( a + b )² adalah + 2ab +
