Question

Tentukan Hasilnya :
1. a(3a+8b)
2. (×+4)(×+15)
3. (6×-9y)(6×-9y)

pakai cara yah :)

Answer 1

. 1. a(3a+8b)=...
a×3a+a×8b= 3a²+8ab
2.(×+4)(×+15)=..
x²+15x+4x+60 = x²=19x=60
3. (6×-9y)(6×-9y)=...
36x²-54xy-54xy+81y² = 36x²-108xy+81y²
semoga membantu

Answer 2

1. a(3a+8b) = 3a kuadrat + 8ab
2. (x+4)(x+15)= X kuadrat + 15x + 4x +60
= X kuadrat + 19x +60
3. (6x-9y) (6x-9y) = 36x kuadrat - 54xy +54xy +81y kuadrat
= 36x kuadrat + 81y kuadrat
