\n" ); document.write( "\n" ); document.write( " $\"2v%5E2-3v%2B1=0\"$
\n" ); document.write( " $\"%282v-1%29%28v-1%29=0\"$
\n" ); document.write( " $\"v=1%2F2\"$ or $\"v=1\"$
\n" ); document.write( ";\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Either $\"cos%28x%29=1%2F2\"$ OR $\"cos%28x%29=1\"$ .\r
