a. 4X - 8Y
3.
a. a2-a-6
b. a2 + 8a + 16
= ( 4 x X ) - (4 x (2y))
= 4x - 8y
b) 8a ( 3ab - 2ab² - 8ab)
= 8a ( 3ab - 8ab) (-2ab²)
=(40 ab - 16a²b²) dibagi 8
= 5ab + 2a²b²
2. sederhanakan
( x + 3)² -= ( x + 3)(x + 3)
= x² + 3x + 3x + 9
= x² + 6x + 9
Jadi (x + 3)² = x² + 6y + 9
3. Selesaikan
a) (a + 2)(a - 3) = a² - 3a + 2a - 6
= a² - a - 6
b) (a + 4)² = ( a + 4) ( a + 4)
= a² + 4a + 4a + 16
= a² + 8a + 16
moga membantu ...^_^
