Whakaoti mō y
y=2x^{3}+3\left(x+4\right)^{2}-7
Whakaoti mō x
x=\frac{\sqrt[3]{2\sqrt{y^{2}-59y+1714}+2y-59}+\sqrt[3]{-2\sqrt{y^{2}-59y+1714}+2y-59}-1}{2}

y=3\left(x^{2}+8x+16\right)+2x^{3}-7
Whakamahia te ture huarua \left(a+b\right)^{2}=a^{2}+2ab+b^{2} hei whakaroha \left(x+4\right)^{2}.
y=3x^{2}+24x+48+2x^{3}-7
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x^{2}+8x+16.
y=3x^{2}+24x+41+2x^{3}
Tangohia te 7 i te 48, ka 41.
