Solution for 3/a^2=4 equation: 


D( a )

a^2 = 0

a^2 = 0

a^2 = 0

1*a^2 = 0 // : 1

a^2 = 0

a = 0

a in (-oo:0) U (0:+oo)

3/(a^2) = 4 // - 4

3/(a^2)-4 = 0

3*a^-2 = 4 // : 3

a^-2 = 4/3

-2 < 0

1/(a^2) = 4/3 // * a^2

1 = 4/3*a^2 // : 4/3

3/4 = a^2

a^2 = 3/4 // ^ 1/2

abs(a) = (3/4)^(1/2)

a = (3/4)^(1/2) or a = -(3/4)^(1/2)

a in { (3/4)^(1/2), -(3/4)^(1/2) }
