25+x^{2}=6^{2}
Tātaihia te 5 mā te pū o 2, kia riro ko 25.
25+x^{2}=36
Tātaihia te 6 mā te pū o 2, kia riro ko 36.
x^{2}=36-25
Tangohia te 25 mai i ngā taha e rua.
x^{2}=11
Tangohia te 25 i te 36, ka 11.
x=\sqrt{11} x=-\sqrt{11}
Tuhia te pūtakerua o ngā taha e rua o te whārite.
25+x^{2}=6^{2}
Tātaihia te 5 mā te pū o 2, kia riro ko 25.
25+x^{2}=36
Tātaihia te 6 mā te pū o 2, kia riro ko 36.
25+x^{2}-36=0
Tangohia te 36 mai i ngā taha e rua.
-11+x^{2}=0
Tangohia te 36 i te 25, ka -11.
x^{2}-11=0
Ko ngā tikanga tātai pūrua pēnei i tēnei nā, me te kīanga tau x^{2} engari kāore he kīanga tau x, ka taea tonu te whakaoti mā te whakamahi i te tikanga tātai pūrua, \frac{-b±\sqrt{b^{2}-4ac}}{2a}, ina tuhia ki te tānga ngahuru: ax^{2}+bx+c=0.
x=\frac{0±\sqrt{0^{2}-4\left(-11\right)}}{2}
Kei te āhua arowhānui tēnei whārite: ax^{2}+bx+c=0. Me whakakapi 1 mō a, 0 mō b, me -11 mō c i te tikanga tātai pūrua, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.
x=\frac{0±\sqrt{-4\left(-11\right)}}{2}
Pūrua 0.
x=\frac{0±\sqrt{44}}{2}
Whakareatia -4 ki te -11.
x=\frac{0±2\sqrt{11}}{2}
Tuhia te pūtakerua o te 44.
x=\sqrt{11}
Nā, me whakaoti te whārite x=\frac{0±2\sqrt{11}}{2} ina he tāpiri te ±.
x=-\sqrt{11}
Nā, me whakaoti te whārite x=\frac{0±2\sqrt{11}}{2} ina he tango te ±.
x=\sqrt{11} x=-\sqrt{11}
Kua oti te whārite te whakatau.
