## Homework Statement

Write the equations of tangent lines to the curve of the implicit function x

^{2}+2x+2y

^{2}-4y=5

that are normal to the line y=x+12

**2. The attempt at a solution**

I know that the slope has to be m=-1

I found the derivative using implicit differentiation:

dy/dx=(-2x-2)/(4y-4)

Now I am unsure how to find the points, please help it is due tomorrow.
