Kua tāruatia ki te papatopenga
\frac{f}{x}-\frac{7x\left(21-2x\right)x}{x}
Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Whakareatia 7x\left(21-2x\right) ki te \frac{x}{x}.
\frac{f-7x\left(21-2x\right)x}{x}
Tā te mea he rite te tauraro o \frac{f}{x} me \frac{7x\left(21-2x\right)x}{x}, me tango rāua mā te tango i ō raua taurunga.
\frac{f-147x^{2}+14x^{3}}{x}
Mahia ngā whakarea i roto o f-7x\left(21-2x\right)x.
