Jawab juseyo

1.x^2 + 7x + 12 = 0
2.x^2 + 2x - 15 = 0
3.x^2 - 2x - 24 = 0
4.x^2 - 9x + 14 = 0

Answer 1

1. (x+3) (x+4) = 0
x = -3 | x= -4
2. (x+5) (x-3) = 0
x= -5 | x= 3
3. (x-6) (x+4) = 0
x = 6 | x = -4
4. (x-7) (x-2) = 0
x =7 | x=2

Answer 2

1) (x+3)(x+4) = 0
     x+3 = 0 atau x+4 = 0
     x = -3             x = -4
    hp = {-4,-3}

2) (x+5)(x-3) = 0
    x+5 = 0 atau x-3 = 0
     x = -5            x = 3
    hp = {-5,3}

3) (x-6)(x+4) = 0
    x-6 = 0 atau x+4 = 0
     x = 6            x = -4
    hp = {-4,6}

4) (x-7)(x-2) = 0
    x-7 = 0 atau x-2 = 0
    x = 7             x = 2
    hp = { 2,7}
