Multiple Choice

Perhatikan persamaan kuadrat di samping, Nilai a, b dan c yang tepat adalah...

Multiple Choice

Dua bilangan (misalkan p dan q) dijumlahkan p+q = 5, dikalikan pxq = -6 yang memenuhi adalah…

p = 2, q =-3

p = -2, q =-3

p = 1, q =-6

p = -1, q = 6

Multiple Choice

Persamaan kuadrat tersebut difaktorkan menjadi…

(x+1)(x+6)=0

(x-1)(x+6)=0

(x+2)(x+3)=0

(x-2)(x+3)=0

Multiple Choice

Jadi akar-akarnya adalah…

-1 dan 6

1 dan -6

-2 dan 3

2 dan 3

Multiple Choice

Dua bilangan (misalkan p dan q) dijumlahkan p+q = 7, dikalikan pxq= 2x6 = 12 yang memenuhi adalah…

p=1, q=12

p=1, q=-12

p=4, q=3

p=-4, q=-3

Multiple Choice

Perhatikan persamaan kuadrat di samping, Nilai a, b dan c yang tepat adalah...

Multiple Choice

Persamaan kuadrat tersebut difaktorkan menjadi…

(x+3)(x+4)

(2x+3)(x+2)

(2x-3)(x+2)

(2x+3)(x+4)

Multiple Choice

Jadi akar-akarnya adalah...
