I need to factor x^2+8x+16 \r
\n" ); document.write( "\n" ); document.write( "So far i have \r
\n" ); document.write( "\n" ); document.write( "(x ) (x ) I know the factors of 16 are 1,2,4,8,16 and they need to add up to 8. where do i go from here?
\n" ); document.write( "

\r\n" );
document.write( "Don't just write the factors down, write them multiplied to give 16,\r\n" );
document.write( "then add them:\r\n" );
document.write( "\r\n" );
document.write( "16=16*1  when added give 16+1=17\r\n" );
document.write( "16=8*2   when added give  8+2=10\r\n" );
document.write( "16=4*4   when added give  4+4=8\r\n" );
document.write( "\r\n" );
document.write( "So now you see that 4+4=8 is what you need, so you write:\r\n" );
document.write( "\r\n" );
document.write( "(x+4)(x+4)\r\n" );
document.write( "\r\n" );
document.write( "And since the factors are the same you \r\n" );
document.write( "write the answer in simplest form:\r\n" );
document.write( "\r\n" );
document.write( "(x+4)²\r\n" );
