Solve for y
y=2\left(x^{2}-4x+6\right)
Solve for x (complex solution)
x=\frac{\sqrt{2y-8}}{2}+2
x=-\frac{\sqrt{2y-8}}{2}+2
Solve for x
x=\frac{\sqrt{2y-8}}{2}+2
x=-\frac{\sqrt{2y-8}}{2}+2\text{, }y\geq 4

y=2\left(4-4x+x^{2}\right)+4
Use binomial theorem \left(a-b\right)^{2}=a^{2}-2ab+b^{2} to expand \left(2-x\right)^{2}.
y=8-8x+2x^{2}+4
Use the distributive property to multiply 2 by 4-4x+x^{2}.
y=12-8x+2x^{2}
Add 8 and 4 to get 12.
