\n" );
document.write( "Hi
\n" );
document.write( "If the sum of 2 numbers is 12 and their product is 32, what are the numbers? 
\n" );
document.write( "Let x = one number
\n" );
document.write( "Let 12-x = the other number 
\n" );
document.write( "x(12-x) = 32
\n" );
document.write( "12x - x^2 = 32
\n" );
document.write( " x^2- 12x + 32 = 0   |Note: ading x^2 and subtracting 12x from both sides
\n" );
document.write( "(x-4)(x-8) = 0
\n" );
document.write( " x = 4, the other 8
\n" );
document.write( "OR x = 8, the other 4
\n" );
document.write( "The two number are 4 and 8 \n" );
document.write( "

\n" );
