Question

x2+12x+36=0 me ajudem

Answer 1

Fórmula:
Δ= b²-4.a.c
x= (-b+/-√Δ)/2.a

Δ= 12²-4.1.36
Δ= 144-144
Δ= 0

x= (-12+/-√0)/2

x'= -12+0/2= -6
x''= 12+0/2= 6

Espero ter ajudado!

Answer 2

x² + 12x + 36 = 0


delta = b² - 4.a.c

a = 1
b = 12
c = 36


delta = 12² - 4.1.36
delta = 144 - 144
delta = 0


x = -b² ± √delta/2.a


x = -12 ± √0/2.1

x = -12 ± 0/2 = -12/2 = -6

s={ -6 }
