[tex]\frac{\frac{2^2}{25}}{-\frac{2}{5}}+\left(-\frac{2}{5}\right)=0[/tex]
[tex]=-\frac{\frac{2^2}{25}}{-\frac{2}{5}}-\frac{2}{5}[/tex]
[tex]\frac{\frac{2^2}{25}}{-\frac{2}{5}}[/tex]
[tex]=-\frac{\frac{2^2}{25}}{\frac{2}{5}}[/tex]
[tex]=-\frac{2^2\cdot \:5}{25\cdot \:2}[/tex]
[tex]-\frac{2^2\cdot \:5}{50}[/tex]
[tex]=-\frac{2}{5}[/tex]
[tex]=-\left(-\frac{2}{5}\right)-\frac{2}{5}[/tex]
[tex]=\frac{2}{5}-\frac{2}{5} = 0[/tex]
Sper că te-am ajutat!
Succes!
