Generally, the equation of some variable x is of the form:

f(x) = 0

To solve the equation above, one should find all the values of variable x such as f(x) = 0 is the correct identity.

Graphically, the roots of some equation f(x) = 0 are the abscisses of the intersection points of function f(x) with axis x:

Therefore, from the above plot of some function
f(x),
we immediately can conclude that the values
x_{1},
x_{2},
x_{3},
x_{4}
are the roots of equation
f(x) = 0.

There are infinity number of different equations (linear, quadratic, cubic, trigonometric, equations with powers and radical, ect.) depending on concrete form of function f(x).
