beserta jalan nya ya 🙂
mohon di jawab ya kakak kakak;)
Tentukan hasil perkalian aljabar berikut ini..
Jawaban:
5y(2y + 7) – 5(2y + 7)
10y² + 35y – 10y – 35
10y² + 25y – 35
no.2
m(m + 1) – 2(m + 1)
m² + m – 2m – 2
m² – m – 2
no.3
2x(x – 2) + 3(x – 2)
2x² – 4y + 3x – 6
2x² – x – 6
no.5
x(3x – 5) + 5(3x – 5)
3x² – 5x + 15x – 25
