Matematika
Persamaan Kuadrat VIII SMP

Pembahasan :
-6x² + 16x = -14
-6x² + 16x + 14 = 0
6x² - 16x - 14 = 0
3x² - 8x - 7 = 0

D = b² - 4ac
D = (-8)² - 4(3)(-7)
D = 64 + 84
D = 148

X1 = (-b + √D)/2a
X1 = (8 + √148)/2.3
X1 = (4 + √37)/3

X2 = (-b - √D)/2a
X2 = (8 - √148)/2.3
X2 = (4 - √37)/3

Hp : {(4 - √37)/3 , (4 + √37)/3}
