6z - 3 = 0
many solutions
It has two equal solutions of 2
It has two solutions and they are: x = 3.230396696 and x = -2.063730029
There are no real solutions. The discriminant (b squared -4ac) is less than 0, so there are 2 imaginary solutions and 0 real ones.
0 = 0 is an identity and not an equation. Equations have solutions, identities do not.

many solutions
There are four solutions to 9x4 plus 27x3 - 4x2 - 12x equals 0. One of the solutions is x = -3.
It has two equal solutions of 2
It has infinitely many solutions.
It has two solutions and they are: x = 3.230396696 and x = -2.063730029
If: n squared -n -90 = 0 Then the solutions are: n = 10 or n = -9
There are no real solutions. The discriminant (b squared -4ac) is less than 0, so there are 2 imaginary solutions and 0 real ones.
Two solutions and they are:- x = 0 and y = 3
