EQUATIONS

Equations were very important in the past. Many mathematicians studied it. For instance: Descartes Cardano Euler

First- degree equations

They are very easy to solve.  You can operate to obtain the value of the unknown.

SECOND DEGREE EQUATIONS

There are three types: incomplete, where you can obtain the value of the unknown easily. incomplete, you need to take out the common factor complete, you should use the formula to resolve it.
