Divide both sides by 2.
x%5E2%2By%5E2-4x%2B16y-50=0

x%5E2%2By%5E2-4x%2B16y=50
x%5E2-4x%2By%5E2%2B16y=50
x%5E2-4x%2B4%2By%5E2%2B16y%2B64=50%2B4%2B64

Write the Equation in Standard Form
2x^2+2y^2-8x+32y-100=0
The other person's answer is WRONG, WRONG, WRONG, and so, we strike it out: cross%28highlight%28%28x-2%29%5E2%2B%28y-8%29%5E2=168%29%29

Try it on your own. You might do a much better job! You never know!!
