We will try to use the quadratic factor procedure so expand the left side of the equation:
\n" ); document.write( "(x-2)(x-7) = -6
\n" ); document.write( "x^2 -7*x -2*x + 2*7 = -6
\n" ); document.write( "x^2 - 9*x + 14 = -6
\n" ); document.write( "x^2 - 9*x + 14 + 6 = 0
\n" ); document.write( "x^2 - 9*x + 20 = 0
\n" ); document.write( "(x-5)(x-4) = 0
\n" ); document.write( "So:
\n" ); document.write( "x-5 = 0 and x-4 = 0
\n" ); document.write( "x = 5 and x = 4 \n" ); document.write( "

\n" );
