4X² – 16x +16=0 ayo di jawab

Jawaban:

x1 = -2, x2 = 2

Penjelasan dengan langkah-langkah:

4x² – 16x + 16 = 0

y × z = 16 × 4 = 64

y + z = -16

y = 8

z = -8

4x² – 16x + 16 = 0

$frac{(4x + 8)(4x - 8)}{4} = 0 \ (x + 2)(4x - 8) = 0 \ \ x1 = x + 2 = 0 \ x1 = - 2 \ \ x2 = 4x - 8 = 0 \ x2 = 4x = 8 \ x2 = 2$
