\n" ); document.write( "\n" ); document.write( " $\"x%5E2%282x-1%29-9%282x-1%29=0\"$
\n" ); document.write( " $\"%282x-1%29%28x%5E2-9%29=0\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"%282x-1%29%28x-3%29%28x%2B3%29=0\"$ \r
\n" ); document.write( "\n" ); document.write( "So either 2x-1 = 0 OR x-3=0 or x+3=0\r
\n" ); document.write( "\n" ); document.write( "x=1/2,3,-3
