Expression is: 9x^2+12xy+4y^2-16z^2\r
\n" ); document.write( "\n" ); document.write( "(Using the identity (a+b)^2 = a^2 + 2ab + b^2\r
\n" ); document.write( "\n" ); document.write( "\"9%2Ax%5E2%2B12%2Ax%2Ay%2B4%2Ay%5E2-16%2Az%5E2+=+%283%2Ax%2B2%2Ay%29%5E2+-+16%2Az%5E2\"\r
\n" ); document.write( "\n" ); document.write( "Now using the identity (a^2 - b^2) = (a+b)(a-b)\r
\n" ); document.write( "\n" ); document.write( "=\"%283%2Ax%2B2%2Ay%2B4%2Az%29%2A%283%2Ax%2B2%2Ay-4%2Az%29\"\r
