MAPEL = MATEMATIKA
KELAS = 8
BAB = OPERASI HITUNG ALJABAR

[tex](2xz + 3y)(4xz - 15y) \\ = 8 {x}^{2} {y}^{2} - 30xyz + 12xyz - 45 {y}^{2} \\ = 8 {x}^{2} {y}^{2} - 18xyz - 45 {y}^{2} [/tex]

semoga membantu

Soal
(2xz + 3y)(4xz - 15y) = ...

Penyelesaian
(2xz + 3y)(4xz - 15y)
=> (2xz × 4xz) - (2xz × 15y) + (3y × 4xz) - (3y × 15y)
=> 8xz^2 - 30xzy + 12xzy - 45y^2
=> 8xz^2 - 18xzy - 45y^2.
