Passi Qosra tas-Soluzzjonijiet

Biex iżżid jew tnaqqas l-espressjonijiet, espandihom biex id-denominaturi tagħhom ikunu l-istess. L-inqas multiplu komuni ta' 7m+2 u m+4 huwa \left(m+4\right)\left(7m+2\right). Immultiplika \frac{7m^{4}}{7m+2} b'\frac{m+4}{m+4}. Immultiplika \frac{3m^{2}}{m+4} b'\frac{7m+2}{7m+2}.

$$\frac{7m^{4}\left(m+4\right)}{\left(m+4\right)\left(7m+2\right)}+\frac{3m^{2}\left(7m+2\right)}{\left(m+4\right)\left(7m+2\right)}$$

Billi \frac{7m^{4}\left(m+4\right)}{\left(m+4\right)\left(7m+2\right)} u \frac{3m^{2}\left(7m+2\right)}{\left(m+4\right)\left(7m+2\right)} għandhom l-istess denominatur, żidhom billi żżid in-numeraturi tagħhom.

$$\frac{7m^{4}\left(m+4\right)+3m^{2}\left(7m+2\right)}{\left(m+4\right)\left(7m+2\right)}$$

Agħmel il-multiplikazzjonijiet fi 7m^{4}\left(m+4\right)+3m^{2}\left(7m+2\right).

$$\frac{7m^{5}+28m^{4}+21m^{3}+6m^{2}}{\left(m+4\right)\left(7m+2\right)}$$

Espandi \left(m+4\right)\left(7m+2\right).

$$\frac{7m^{5}+28m^{4}+21m^{3}+6m^{2}}{7m^{2}+30m+8}$$
