Kua tāruatia ki te papatopenga
\frac{9}{5}z\times 5z+\frac{9}{5}z\left(-3\right)
Whakamahia te āhuatanga tohatoha hei whakarea te \frac{9}{5}z ki te 5z-3.
\frac{9}{5}z^{2}\times 5+\frac{9}{5}z\left(-3\right)
Whakareatia te z ki te z, ka z^{2}.
9z^{2}+\frac{9}{5}z\left(-3\right)
Me whakakore te 5 me te 5.
9z^{2}+\frac{9\left(-3\right)}{5}z
Tuhia te \frac{9}{5}\left(-3\right) hei hautanga kotahi.
9z^{2}+\frac{-27}{5}z
Whakareatia te 9 ki te -3, ka -27.
9z^{2}-\frac{27}{5}z
Ka taea te hautanga \frac{-27}{5} te tuhi anō ko -\frac{27}{5} mā te tango i te tohu tōraro.
\frac{9}{5}z\times 5z+\frac{9}{5}z\left(-3\right)
Whakamahia te āhuatanga tohatoha hei whakarea te \frac{9}{5}z ki te 5z-3.
\frac{9}{5}z^{2}\times 5+\frac{9}{5}z\left(-3\right)
Whakareatia te z ki te z, ka z^{2}.
9z^{2}+\frac{9}{5}z\left(-3\right)
Me whakakore te 5 me te 5.
9z^{2}+\frac{9\left(-3\right)}{5}z
Tuhia te \frac{9}{5}\left(-3\right) hei hautanga kotahi.
9z^{2}+\frac{-27}{5}z
Whakareatia te 9 ki te -3, ka -27.
9z^{2}-\frac{27}{5}z
Ka taea te hautanga \frac{-27}{5} te tuhi anō ko -\frac{27}{5} mā te tango i te tohu tōraro.
