a^2 = 0
a^2 = 0
a^2 = 0
1*a^2 = 0 // : 1
a^2 = 0

a in (-oo:0) U (0:+oo)
1.5625 = 1/(a^2) // - 1/(a^2)
1.5625-(1/(a^2)) = 0
1.5625-a^-2 = 0
-1*a^-2 = -1.5625 // : -1
a^-2 = 1.5625
-2 < 0
1/(a^2) = 1.5625 // * a^2
1 = 1.5625*a^2 // : 1.5625
0.64 = a^2
a^2 = 0.64 // ^ 1/2
abs(a) = 0.64^(1/2)
a = 0.64^(1/2) or a = -0.64^(1/2)
