Tentukan hasil perkalian bentuk aljabar berikut:
1. -5p³ (6p-3q) =
2. -2mn (3m-4mn-7n²) =
3. (2x-5) (2x+3) =
4. (8-5x) (9-5x) =
5. (9+12y) (9-12y) =
6. (x²+y²) (x²+y²)=
7. (x²+5x) (x²-10x) =
8. (4x²-2y) (4x²-5y) =
*pake cara nya ya.

2. - 6m²n + 8m²n² + 14mn³
3. 4x² + 6x - 10x - 15 = 4x² - 4x - 15
4. 72 - 40x - 45x + 25x² = 72 - 85x + 25x² = 25x² - 85 + 72
5. 81 - 108y + 108y - 144y² = 81 - 144y²= - 144y² + 81 = 144y² - 81
6. x⁴ + x²y² + x²y² + y⁴ = x⁴ + 2x²y² + y⁴
7. x⁴ - 10x³ + 5x³ - 50x² = x⁴ - 5x³ - 50x² klau lebih sederhana lagi atau di faktorkan lagi x² ( x² - 5x - 50 )
8. 16x⁴ - 20x²y - 8x²y + 10y² = 16x⁴ - 28x²y + 10y²
