f(x)=2x²-4x-13 in the form of f(x)=a(x+h)²+k
\n" ); document.write( "

\n" ); document.write( "Complete the square\r
\n" ); document.write( "\n" ); document.write( " $\"2x%5E2+-+4x++-+13\"$ ; factor out a 2 from left side
\n" ); document.write( "

\n" ); document.write( " $\"2%28x%5E2+-+2x%29+-+13\"$ ; complete the square
\n" ); document.write( "

\n" ); document.write( " $\"2%28x%5E2+-+2x+%2B+1%29+-+13+-+2\"$
\n" ); document.write( "

\n" ); document.write( " $\"2%28x-1%29%5E2+-+15\"$
\n" ); document.write( "

\n" ); document.write( "final form:
