Solve for x
x=4\left(y+4\right)^{2}
Solve for y (complex solution)
y=-\frac{\sqrt{x}}{2}-4
y=\frac{\sqrt{x}}{2}-4
Solve for y
y=-\frac{\sqrt{x}}{2}-4
y=\frac{\sqrt{x}}{2}-4\text{, }x\geq 0

64+32y+4y^{2}=x
Use binomial theorem \left(a+b\right)^{2}=a^{2}+2ab+b^{2} to expand \left(8+2y\right)^{2}.
x=64+32y+4y^{2}
Swap sides so that all variable terms are on the left hand side.
