factoring a ___ f(x) = 2(x^2 + 4x) + 5\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "completing the square ___ f(x) = 2(x^2 + 4x + 4) + 5 - (2 * 4)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "f(x) = 2(x + 2)^2 - 3\r
\n" ); document.write( "
