If xy = 3, xz = 4, and yz = 6, Find the value of x^2 + y^2 + z^2
\n" ); document.write( "
\r\n" );
document.write( "\"yz=6\", so \"z=6%2Fy\", plug that in\r\n" );
document.write( "\r\n" );
document.write( "\"xz=4\" and get \"x%286%2Fy%29=4\" or \"6x%2Fy=4\" or \"6x=4y\" or \"y=6x%2F4=3x%2F2\"\r\n" );
document.write( "\r\n" );
document.write( "Plug that in \"xy=3\"\r\n" );
document.write( "\r\n" );
document.write( "\"x%283x%2F2%29=3\", or \"3x%5E2%2F2=3\" or \"3x%5E2=6\" or \"x%5E2=2\"\r\n" );
document.write( "\r\n" );
document.write( "--------------------------------------------------------------\r\n" );
document.write( "\r\n" );
document.write( "\"xy=3\", so \"x%5E2y%5E2=9\" so \"y%5E2=9%2Fx%5E2=9%2F2\"\r\n" );
document.write( "\r\n" );
document.write( "\"xz=4\", so \"x%5E2z%5E2=16\" so \"z%5E2=16%2Fx%5E2=16%2F2=8\"\r\n" );
