Answer:

C. x = 1/2

Explanation:

[tex]\sf \rightarrow x^2 = \dfrac{1}{4}[/tex]

[tex]\sf \rightarrow x=\sqrt{\dfrac{1}{4}},\:x=-\sqrt{\dfrac{1}{4}}[/tex]

[tex]\sf \rightarrow x=\dfrac{1}{2},\:x=-\dfrac{1}{2}[/tex]

As asked for positive solution (+)

[tex]\sf \rightarrrow \sf \rightarrow x=\dfrac{1}{2}[/tex]
