Question

entukan akar akar persamaan kuadrat dengan memfaktorkan x²-8x+15=0​

Answer 1

Jawaban:

3 dan 5

Penjelasan dengan langkah-langkah:

x² - 8x + 15 = 0

( x - 3 ) ( x - 5 ) = 0

• x - 3 = 0

x = 3

• x - 5 = 0

x = 5

Answer 2

Jawaban:

x = 3, x = 5

Penjelasan dengan langkah-langkah:

x² - 8x + 15 = 0

(...) × (...) = 15

(...) + (...) = -8

(-3) × (-5) = 15

(-3) + (-5) = -8

(x - 3)(x - 5) = 0

x - 3 = 0

x = 3

x - 5 = 0

x = 5
