# Solve equations online

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

f (x) =0

To solve this equation above, one should find all the values of variable x such as f (x) equals to zero.

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

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)

The calculator below is able to find roots of many different forms of equations.
