Kua tāruatia ki te papatopenga
15x^{5}-3x^{5}\times 4
Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te 3 me te 2 kia riro ai te 5.
15x^{5}-12x^{5}
Whakareatia te 3 ki te 4, ka 12.
3x^{5}
Pahekotia te 15x^{5} me -12x^{5}, ka 3x^{5}.
5\times 15x^{5-1}+3\left(-12x^{2}\right)x^{3-1}
Ko te pārōnaki o tētahi pūrau ko te tapeke o ngā pārōnaki o ōna kīanga tau. Ko te pārōnaki o tētahi kīanga tau pūmau ko 0. Ko te pārōnaki o te ax^{n} ko te nax^{n-1}.
75x^{5-1}+3\left(-12x^{2}\right)x^{3-1}
Whakareatia 5 ki te 15.
75x^{4}+3\left(-12x^{2}\right)x^{3-1}
Tango 1 mai i 5.
75x^{4}+\left(-36x^{2}\right)x^{3-1}
Whakareatia 3 ki te -3\times 4x^{2}.
75x^{4}+\left(-36x^{2}\right)x^{2}
Tango 1 mai i 3.
