\frac{2}{\left(x+2\right)\left(x-3\right)^{2}}-\frac{3x}{5\left(x^{2}-3\right)}
Tegurda x^{3}-4x^{2}-3x+18. Tegurda 5x^{2}-15.
\frac{2\times 5\left(x^{2}-3\right)}{5\left(x+2\right)\left(x-3\right)^{2}\left(x^{2}-3\right)}-\frac{3x\left(x+2\right)\left(x-3\right)^{2}}{5\left(x+2\right)\left(x-3\right)^{2}\left(x^{2}-3\right)}
Avaldiste liitmiseks või lahutamiseks laiendage need, et neil oleksid ühised nimetajad. \left(x+2\right)\left(x-3\right)^{2} ja 5\left(x^{2}-3\right) vähim ühiskordne on 5\left(x+2\right)\left(x-3\right)^{2}\left(x^{2}-3\right). Korrutage omavahel \frac{2}{\left(x+2\right)\left(x-3\right)^{2}} ja \frac{5\left(x^{2}-3\right)}{5\left(x^{2}-3\right)}. Korrutage omavahel \frac{3x}{5\left(x^{2}-3\right)} ja \frac{\left(x+2\right)\left(x-3\right)^{2}}{\left(x+2\right)\left(x-3\right)^{2}}.
\frac{2\times 5\left(x^{2}-3\right)-3x\left(x+2\right)\left(x-3\right)^{2}}{5\left(x+2\right)\left(x-3\right)^{2}\left(x^{2}-3\right)}
Kuna murdudel \frac{2\times 5\left(x^{2}-3\right)}{5\left(x+2\right)\left(x-3\right)^{2}\left(x^{2}-3\right)} ja \frac{3x\left(x+2\right)\left(x-3\right)^{2}}{5\left(x+2\right)\left(x-3\right)^{2}\left(x^{2}-3\right)} on sama nimetaja, lahutage nende lugejad.
\frac{10x^{2}-30-3x^{4}+18x^{3}-27x^{2}-6x^{3}+36x^{2}-54x}{5\left(x+2\right)\left(x-3\right)^{2}\left(x^{2}-3\right)}
Tehke korrutustehted võrrandis 2\times 5\left(x^{2}-3\right)-3x\left(x+2\right)\left(x-3\right)^{2}.
