(3x+2y)pangkat 2 tolong di bantuu yaa secepatny...

=(3x+2y)(3x+2y)
=9x^2+12xy+4y^2

Bab Eksponensial
Matematika SMP Kelas VIII

1] (3x + 2y)²
= (3x)² + 2 . 3x . 2y + (2y)²
= 9x² + 12xy + 4y²

2] (2x + 3y)⁴
= (2x)⁴ + 4 . (2x)³ 3y + 6 (2x)² (3y)² + 4 . 2x . (3y)³ + (3y)⁴
= 16x² + 96x³y + 216x²y² + 216xy³ + 81y⁴
