How to find the root of equation

An equation is an equation of the form f (x, y, ...) = g (x, y, ..), where f and g are functions of one or more variables.

To find the root of the equation is to find a set of arguments for which this equality holds.

You will need

  • Knowledge of mathematical analysis.



Suppose you have an equation of the form: x + 2 = x / 5. To begin with, we transfer all the components of this equality from the right to the left, changing the sign of the component to the opposite one. On the right side of this equation there will be zero, that is, we get the following: x + 2-x / 5 = 0.


We give such terms. We obtain the following: 4x / 5 + 2 = 0.


Further from the obtained reduced equationFind an unknown term, in this case it is x. The resulting value of the unknown variable u will be the solution of the original equation. In this case, we get the following: x = -2.5.
