anonymous · Answer

why dont you cross add...
meaning that (a+b)+(a-b)=o and 2a+a= 3 a
i not what you are trying to solve here but hope this helps

$$
\frac{2 a}{a+b}+\frac{a-b}{a} =\frac{3 a^2-b^2}{a (a+b)}
$$

anonymous · Answer

$$
\frac{2 a}{a+b}+\frac{a-b}{a} =\frac{2a^2 + a^2 -b^2}{a (a+b)}
=\frac{3 a^2-b^2}{a (a+b)}

$$
