Solve for y
y=2\left(x^{2}+4x+7\right)
Solve for x (complex solution)
x=-\frac{\sqrt{2y-12}}{2}-2
x=\frac{\sqrt{2y-12}}{2}-2
Solve for x
x=-\frac{\sqrt{2y-12}}{2}-2
x=\frac{\sqrt{2y-12}}{2}-2\text{, }y\geq 6

y=2\left(x^{2}+4x+4\right)+6
Use binomial theorem \left(a+b\right)^{2}=a^{2}+2ab+b^{2} to expand \left(x+2\right)^{2}.
y=2x^{2}+8x+8+6
Use the distributive property to multiply 2 by x^{2}+4x+4.
y=2x^{2}+8x+14
Add 8 and 6 to get 14.
