Respuesta :

Answer:

z = 1/9   and    z = 1

Step-by-step explanation:

[tex]-9 z^{2} + 10z - 1 = 0[/tex]

[tex](-9z+1)(z-1) = 0[/tex]

You can check the answer using foil method

Then,

[tex](-9z+1) = 0[/tex]

[tex]-9z = -1[/tex]

[tex]z = 1/9[/tex]

[tex](z-1) = 0[/tex]

[tex]z = 1[/tex]

Answers:

[tex]z = 1/9[/tex]

[tex]z = 1[/tex]
