$\"3x%5E2-10x=-7\"$
\n" ); document.write( " $\"3x%5E2-10x%2B7=0\"$
\n" ); document.write( "You want to find two numbers that:
\n" ); document.write( "multiply to 7*3=21
\n" ); document.write( "and add to -10
\n" ); document.write( "therefore -3 and -7\r
\n" ); document.write( "\n" ); document.write( " $\"3x%5E2-3x-7x%2B7=0\"$
\n" ); document.write( " $\"3x%28x-1%29-7%28x-1%29=0\"$
\n" ); document.write( " $\"%283x-7%29%28x-1%29=0\"$ \r
\n" ); document.write( "\n" ); document.write( "So,
\n" ); document.write( " $\"3x-7=0\"$
\n" ); document.write( " $\"3x=7\"$
\n" ); document.write( " $\"x=7%2F3\"$
\n" ); document.write( "or
\n" ); document.write( " $\"x-1=0\"$
\n" ); document.write( " $\"x=1\"$ \r
\n" ); document.write( "\n" ); document.write( "So therefore, x=7/3 or x=1 .
\n" ); document.write( " \n" ); document.write( "

\n" );
