1.X²+X -6 = 0 2.X²+2X+1 = 0 3.X² -2 X -8=0 4.3X²+5X + 2 = 0

1. x²+x-6 = 0
(x+3)(x-2) = 0
x = -3 atau x = 2
2. x²+2x+1 = 0
(x+1)(x+1) = 0
x = -1
3. x²-2x-8 = 0
(x+2)(x-4) = 0
x = -2 atau x = 4
4. 3x²+5x+2 = 0
3x²+3x+2x+2 = 0
3x(x+1)+2(x+1) = 0
(3x+2)(x+1) = 0
x = -2/3 atau x = -1

ini jawabannnya no 4 belum
