How to remove the module</a>

A module in mathematics is called an absolute value.

Denoted by two vertical lines: | x |.

You will need

  • Knowledge in the field of mathematical analysis and the ability to solve inequalities.

Instructions

    1

Suppose you have a certain expression under the module sign, for example | x-5 | = x + 2. First open the sign of the module with the sign "+". That is, we simply omit it. We get the following: x-5 = x + 2.

    2

Lower the sign of the module with the sign "-", that is, multiply the submodule expression by -1 and remove the sign of the module. We obtain the following inequality: -x + 5 = x + 2.

    3

We solve both equations obtained. The roots of these equations are the roots of the original equation with the sign of the modulus.
