Tentukan Akar Persamaan Kuadrat Dengan Cara Membentuk Kuadrat Sempurna Dan Rumus Kuadratik X²+7x+6=0

X² + 7x + 6 = 0
( x + 6 ) ( x + 1 ) = 0

x1 :
x + 6 = 0
x = -6

x2 :
x + 1 = 0
x = -1

jawaban nya : x1 = -6 dan x2 = -1

a = 1
b = 7
c = 6

D = b² – 4 x a x c
D = 7² – 4 x 1 x 6 = 49 – 24
D = 25

x1 = ( -b + √D ) / 2 a
x1 = ( -7 + √25 ) / 2
x1 = ( -7 + 5 ) / 2
x1 = -2 / 2
x1 = -1

x2 = ( -b – √D ) / 2a
x2 = ( -7 – 5 ) / 2
x2 = -12 / 2
x2 = -6
