If the axes are shifted to the point `(1,-2)` without rotation, what do the following equations become? `2x^2+y^2-4x+4y=0` `y^2-4x+4y+8=0`

Explanation

To solve the problem of shifting the axes to the point (1, -2) without rotation for the given equations, we will follow these steps:

### Step 1: Understand the Shift in Coordinates
When we shift the axes to a new point (h, k), the new coordinates (x', y') are related to the old coordinates (x, y) by the equations:
- \( x' = x - h \)
- \( y' = y - k \)

In this case, \( h = 1 \) and \( k = -2 \). Therefore, we have:
