$\"x%5E2%2By%5E2%2B136=4%285y-3x%29\"$
\n" ); document.write( " $\"x%5E2%2By%5E2%2B136=20y-12x\"$
\n" ); document.write( " $\"x%5E2%2B12x%2By%5E2-20y=-136\"$
\n" ); document.write( " $\"%28x%5E2%2B12x%2B36%29%2B%28y%5E2-20y%2B100%29=-136%2B36%2B100\"$
\n" ); document.write( " $\"%28x%2B6%29%5E2%2B%28y-10%29%5E2=0\"$
\n" ); document.write( " $\"%28y-10%29%5E2=-%28x%2B6%29%5E2\"$
\n" ); document.write( " $\"y-10=0+%2B-+sqrt%28-%28x%2B6%29%5E2%29\"$
\n" ); document.write( " $\"y=-10+%2B-+sqrt%28-%28x%2B6%29%5E2%29\"$
