2. Componendo and dividendo is a method of
simplification in algebra, which is based on fractions
that are in proportion.
In this method we have 5 types of relationships
1. Invertendo
2. Alternendo
3. Componendo
4. Dividendo
5. Componendo - Dividendo
4. Example
Lets see the application of Componendo – Dividendo
Find the value of x in this equation (6+x)/(6-x)=2 ?
{(6+x)+(6-x)}/ {(6+x)-(6-x)}= (2+1)/(2-1)
12/2x=3
6/x=3
x=2
