[Jawaban] There are four steps for converting the equation $x^2+y^2+12 x+2 y-1=0$ into standard form by completing the square. Complete the last step. 1. Group the $x$ terms together and the $y$ terms together, and move the constant term to the other side of the equation. $x^2+12 x+y^2+2 y=1$ 2. Determine $(b \div 2)^2$ for the $x$ and $y$ terms. $(12 \div 2)^2=36 \text { and }(2 \div 2)^2=1$ 3. Add the values to both sides of the equation. $x^2+12 x+36+y^2+2 y+1=1+36+1$ 4. Write each trinomial as a binomial squared, and simplify the right side. $(x+\square)^2+(y+\square)^2=\square
