\n" ); document.write( " $\"+5x%5E2%2B40x%2B80=0+\"$ ...simplify, both sides divide by $\"5\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"+x%5E2%2B8x%2B16=0+\"$ .......factor\r
\n" ); document.write( "\n" ); document.write( " $\"+x%5E2%2B4x%2B4x%2B16=0+\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"+%28x%5E2%2B4x%29%2B%284x%2B16%29=0+\"$ \r
