[tex]16x^2-1=0 2:x[/tex] 

[tex] 16x^2=1 [/tex]   [tex]|Add \ 1 \ to \ both \ sides|[/tex]

[tex]x^2= \dfrac{1}{16} [/tex]   [tex]|Divide \ both \ sides \ by \ 16|[/tex]

[tex]x^2= \sqrt{\dfrac{ \sqrt{1}}{ \sqrt{16}}}[/tex]  [tex]|Take \ the \ square \ root \ of \ both \ sides|[/tex]

[tex]x= \dfrac{1}{4} [/tex]
