Tolong bantu jawab pake cara : 1. x^2 + 8x + 12 : x + 2 2. Menggunakan pola bilangan pascal : (2y + 4)^3 3. Faktorkan = 25x^2 - (x - y)^2 4. x^2 - x / x^2 + 7x

1. x² + 8x + 12 : x + 2 = x + 6 [Cara di GAMBAR]

2. (2y + 4)³
= (2y)³ + 3(2y)².4 + 3(2y).4² + 4³
= 8y³ + 12y².4 + 6y.16 + 64
= 8y³ + 48y² + 96y + 64

3. 25x² - (x - y)²
= (5x + (x - y)) (5x - (x - y))
= (5x + x - y) (5x - (x - y))
= (6x - y) (4x + y)

4. x² - x / x² + 7x - 8
= x(x - 1) / (x - 1) / (x + 8)
= x / x + 8
