±1/2. The equation $4x^{2} =1$ has two possible solutions +1/2 and -1/2.

The problem is a quadratic equations and it can be solved using the equation $x=-b±\frac{\sqrt{b^{2} -4ac} }{2a}$ .

Ordering the quadratic equation given in the problem, we obtain $4x^{2} -1=0$ where a = 4, b = 0, and c = -1

Substituting the values

$x=±\frac{\sqrt{-4(4)(-1)} }{2(4)}=±\frac{\sqrt{16}}{8} =±\frac{4}{8} \\x=±\frac{1}{2}$
