Whakaoti mō y
y=\frac{\left(x+5\right)^{2}-5}{5}
Whakaoti mō x (complex solution)
x=-\sqrt{5\left(y+1\right)}-5
x=\sqrt{5\left(y+1\right)}-5
Whakaoti mō x
x=-\sqrt{5\left(y+1\right)}-5
x=\sqrt{5\left(y+1\right)}-5\text{, }y\geq -1

Kua tāruatia ki te papatopenga
y=\frac{1}{5}\left(x^{2}+10x+25\right)-1
Whakamahia te ture huarua \left(a+b\right)^{2}=a^{2}+2ab+b^{2} hei whakaroha \left(x+5\right)^{2}.
y=\frac{1}{5}x^{2}+2x+5-1
Whakamahia te āhuatanga tohatoha hei whakarea te \frac{1}{5} ki te x^{2}+10x+25.
y=\frac{1}{5}x^{2}+2x+4
Tangohia te 1 i te 5, ka 4.
