you can find it by counting how many numbers they are in the equation
An identity equation has infinite solutions.
It will depend on the equation.
If the discriminant of a quadratic equation is less then 0 then it will have no real solutions.
If the highest degree of an equation is 3, then the equation must have 3 solutions. Solutions can be: 1) 3 real solutions 2) one real and two imaginary solutions.
It has the following solutions.
The quadratic equation will have two solutions.
Infinitely many

An equation can be determine to have no solution or infinitely many solutions by using the square rule.
There are two distinct real solutions.
They each typically have two solutions, a positive one and a negative one.
As many solutions as there are points in the domain.
