Answer 1

a=1 b=8 c=16
Delta= b^2-4ac
Delta= 8^2-4(1)(16)
Delta= 64-64
Delta= 0

x= -b+Raiz de Delta/ 2.a
x= -8+ 0/ 2.1
x= -8:2/2:2
x= -4/ 1
x= -4
x= -b-Raiz de Delta/ 2.a
x= -8- 0/ 2.1
x= -8:2/2:2
x= -4/ 1
x= -4
S= {-4;-4}

Answer 2

Resposta:

x= -b+Raiz de Delta/ 2.a

x= -8+ 0/ 2.1

x= -8:2/2:2

x= -4/ 1

x= -4

x= -b-Raiz de Delta/ 2.a

x= -8- 0/ 2.1

x= -8:2/2:2

x= -4/ 1

x= -4

S= {-4;-4
