step 1 - expand to get
\n" ); document.write( " $\"9f%5E2+-6f+%2B+1+%2B+15f+=+5\"$
\n" ); document.write( "combine like terms to get
\n" ); document.write( " $\"9f%5E2+%2B+9f+%2B+1+=+5\"$
\n" ); document.write( "set = 0 to get
\n" ); document.write( " $\"9f%5E2+%2B+9f+-+4+=+0\"$
\n" ); document.write( "factoring we get
\n" ); document.write( " $\"%283f-1%29%283f%2B4%29+=+0\"$
\n" ); document.write( "solving for f, we get
\n" ); document.write( "f = 1/3
\n" ); document.write( "or
\n" ); document.write( "f = -4/3 \n" ); document.write( "

\n" );
