Whakaoti mō y
y=\frac{4z\left(x+z\right)+x^{2}+3}{2}
Whakaoti mō x
x=-2z+\sqrt{2y-3}
x=-2z-\sqrt{2y-3}\text{, }y\geq \frac{3}{2}
Tohaina
Kua tāruatia ki te papatopenga
2y=4z^{2}+4zx+x^{2}+3
Whakamahia te āhuatanga tohatoha hei whakarea te 4z ki te z+x.
2y=x^{2}+4xz+4z^{2}+3
He hanga arowhānui tō te whārite.
\frac{2y}{2}=\frac{\left(x+2z\right)^{2}+3}{2}
Whakawehea ngā taha e rua ki te 2.
y=\frac{\left(x+2z\right)^{2}+3}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
