Question

Tentukan penyelesaiam x²-5x+6=0

Answer 1

X² - 5x + 6 = 0
Jika dibelakang x tidak angka (1), maka menggunakan rumus..
... * ... = c
... + ... = b

... * ... = 6
... + ... = -5

-2 * -3 = 6
-2 + (-3) = -5
Maka,
(x - 2) (x - 3)
x1 - 2 = 0
x1 = 2

x2 - 3 = 0
x2 = 3

HP = {x1, x2}
HP = {2, 3}

Answer 2

(X2-5x+6) (X-2)(X-3) X=2 &X=3
