Y² -16 y + 64 = 0
(y-8)(y-8) = (y-8)²
y = 8
d = 0 e a = 0
Existem duas raízes reais iguais.

Y= 8 ! Esta é a resposta ! Pois : y= 16+Raiz quadrada de zero , sôbre 2 , portanto , ficará 16/2 +8 , Certo ? Porque vai dar : 256 -256 = 0 (delta) !* que seria : 16 ao quadrado=256 e 4x64=256 ! Entendeu ?*
