Solve by completing the square\r
\n" ); document.write( "\n" ); document.write( " $\"x%5E2%2B2=2x\"$
\n" ); document.write( " $\"x%5E2-2x%2B2=0\"$
\n" ); document.write( " $\"x%5E2-2x%2B2-2=0-2\"$
\n" ); document.write( " $\"x%5E2-2x=-2\"$
\n" ); document.write( " $\"%28x%5E2-2x%2B1%29=-2%2B1\"$
\n" ); document.write( " $\"%28x-1%29%5E2=-1\"$
\n" ); document.write( " $\"sqrt%28%28x-1%29%5E2%29=sqrt%28-1%29\"$
\n" ); document.write( " $\"x-1=%2B-i\"$
\n" ); document.write( " $\"x-1%2B1=1%2B-i\"$
\n" ); document.write( "x=1-i and x=1+i
\n" ); document.write( "If you are not using imaginary numbers yet, there is no solution.
