I hope this helps:\r
\n" ); document.write( "\n" ); document.write( "(3X + 2)(3X-2)
\n" ); document.write( "If you mutiply it out it comes to:
\n" ); document.write( "9X^2 -6X +6X -4
\n" ); document.write( "Your -6X +6X cancel each other out.
\n" ); document.write( "you will end up with:
\n" ); document.write( "9X^2 -4
\n" ); document.write( "I don't mean to confuse you, but I look at it as your 9 and 4 are perfect squares. 3^2 and 2^2. If you break it down you will come back the the original equation.
\n" ); document.write( "(3X + 2) (3X-2)\r
\n" ); document.write( "\n" ); document.write( "I hope this helps\r
