You can put this solution on YOUR website!
I'll solve this part b by myself. \r

\r\n" );
document.write( "First, you should multiply the two known factors together: \r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "which simplifies to:\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "after you get that, one method to solve this problem is to do trial and error:\r\n" );
document.write( "\r\n" );
document.write( "After a while, you should get:\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The simplified version is:\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Now, you can see that , and .\r\n" );
document.write( "\r\n" );
document.write( "Thus we get the ANSWER :  a = .\r\n" );
document.write( "\r\n" );
