Whakaoti mō k
k=\left(1-x\right)\left(5x+2\right)
Whakaoti mō x (complex solution)
x=\frac{\sqrt{49-20k}+3}{10}
x=\frac{-\sqrt{49-20k}+3}{10}
Whakaoti mō x
x=\frac{\sqrt{49-20k}+3}{10}

Kua tāruatia ki te papatopenga
2-k=5x^{2}-3x
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-k=5x^{2}-3x-2
Tangohia te 2 mai i ngā taha e rua.
\frac{-k}{-1}=\frac{\left(x-1\right)\left(5x+2\right)}{-1}
Whakawehea ngā taha e rua ki te -1.
k=\frac{\left(x-1\right)\left(5x+2\right)}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
k=-\left(x-1\right)\left(5x+2\right)
Whakawehe \left(-1+x\right)\left(2+5x\right) ki te -1.
