\n" );
document.write( "Hi,
\n" );
document.write( "6x^2 + 7x = 3
\n" );
document.write( "6x^2 + 7x - 3 = 0   |Subtracting 3 from both sides of the EQ
\n" );
document.write( "(3x -1)(2x +3)= 0    | Note:SUM of the outside terms(9x) and the inside terms(-2x) = 7x
\n" );
document.write( "The Idea is to match Up the -1 and 3 with the 2 & 3 so one gets that 7x
\n" );
document.write( "Checking the factoring Using FOIL

document.write( "F	First terms
