Swap the 2nd and 3rd terms on the left to get the terms together
for each letter:
Subtract the constant term from both sides:
Factor out 16 out of the first two terms, and 1 out of
the last two terms:
We complete the square inside the first parentheses:
1. Multiply the coefficient of x, which is 4, by one-half, getting 2.
2. Square 2, getting 4.
3. Add +4 at the end of the first parentheses.
4. Since the number in front of the parentheses is 16, adding 4 inside
the parentheses amounts to adding 16∙4 or 64 to the left side, so
we add 64 to the right side:
We complete the square inside the second parentheses:
1. Multiply the coefficient of y, which is -2, by one-half, getting -1.
2. Square -1, getting +1.
3. Add +1 at the end of the first parentheses.
4. Since the number in front of the parentheses is 1, adding 4 inside
the parentheses amounts to adding 1∙1 or 1 to the left side, so
we add 1 to the right side:
Next we factor the quadratics in the parentheses:
This does not represent a conic because the left side is positive
and the right side is negative.
We get 1 on the right side by dividing each term by -2
We divide top and bottom of the first fraction by 16
If this were a real conic, there would not be a negative number
on the bottom of either term, but only positive numbers.
