A) x(x - 11) = 0
x = 0
x-11 = 0 --> x = 11
S --> x' = 0
x"= 11
**********************************************
B) Usando Báskara
x(x - 11) = 0
x² - 11x = 0 .............a = 1
b = -11
c = 0
Δ = b²-4ac = (-11)² - 4.1.0 = 121 =0 = 121
√Δ= +-√121 = +-11
x' = (11+11)/2 = 22/2 = 11
x"= (11- 11)/2 = 0/2 = 0
S --> x' = 0
x"= 11
x = 0
x-11 = 0 --> x = 11
S --> x' = 0
x"= 11
