(3a-4)^3
= (3a-4).(3a-4)²
= (3a-4).((3a)²+2.3a.(-4)+(-4)²)
= (3a-4).(9a²-24a+16)
= 3a.9a²+(-4).9a²+3a.(-24a)+(-4).(-24a)
+ 3a.16+(-4).16
= 27a^3 -36a²-72a²+96a+48a-64
= 27a^3 -108a²+144a-64
FAKTOR :
1) 4y+6 = 2(2y+3)
2) x²-5x = x(x+(-5)) atau x(x-5)
3) 2x^3 + 4x² - 6x = 2x(x²+2x-3)
4) a²b +ab²+ab = ab(a+b+1)
5) 6x²y-9x²y² = 3x²y(2-3y)
