WHAKAMĀRAMA

Ko ngā whārite he pūrua tētahi o ngā taurangi. Ko te tauira māmā: y = x2. Kāore hoki he taupū nui atu i te pūrua i roto i te whārite.

An equation in which one of the variables is to the power of two. The simplest example is y = x2. There are no higher powers (exponents) in the equation.

Tauira KŌrero

Whakaotia ēnei whārite pūrua.

Ina whakaaturia te whārite pūrua ki te kauwhata, he unahi te āhua.

Whakatauwehea te whārite pūrua.

WhakamĀrama Āpitihanga

He pānga pūrua te whārite y = x2, he tauira o te pānga rārangi-kore nā te mea he kōpiko te rārangi o tōna kauwhata. Ka kīia hoki he whārite kōpiko. Arā:

He whārite pūrua tenei: (x + 3)2 = 0
Ka whakawhānuitia tēnei whārite pūrua: x2 + 6x + 9 = 0

He whārite pūrua anō tēnei: x2 + 4x + 3 = 0
Ka whakatauwehea tēnei whārite pūrua: (x + 1)(x + 3)
