X2+8x+12=0 menggunakan rumus ABC

langsung aja y

x² + 8x + 12 = 0
a = 1
b = 8
c = 12

X1,2 = -b ± √b² - 4ac / 2a

X1,2 = -8 ± √8² - 4.1.12 / 2.1

X1,2 = -8 ± √ 64 - 48 / 2

X1,2 = -8 ± √16 / 2

X1,2 = -8 ± 4 /2

X1,2 = 2(-4 ± 2) / 2

X1,2 = -4 ± 2

maka

X1 = -4 + 2 = -2
X2 = -4 - 2 = -6

HP {-2 , -6}

semoga berguna +_+
