Consider the equation,
12z2=3
Left hand side =12z2 and Right hand side =3.
From above equation,
Left hand side =12z2 is always positive for any values of z.
Fight hand side =3 is negative .
To get,
Left hand side is not equal to the right hand side.
Since left hand side is always positive for any values of z except if z is zero or undefined , it can be never equal a negative number and right hand side is negative. Then,
The equation 12z2=3 has no solution.
