Question

Fungsi persamaan kuadrat mempunyai akar 4 dan 6 maka persamaan kuadratnya adalah ...

Answer 1

X² - (x1 + x2)x + x1 . x2 = 0
x² - (4 + 6)x + 4 . 6 = 0
x² - 10x + 24 = 0

Answer 2

X = 4
• (x-4) = 0

x = 6
• (x-6) = 0

(x-4)(x-6) = 0
• x^2 -10x + 24 = 0

cara lain :

x1 + x2 = 4+6 = 10
x1 × x2 = 4×6 = 24

x^2 -(x1+x2)x + (x1 × x2) = 0
masukan nilainy
• x^2 -10x +24 = 0
