w width
\n" ); document.write( "L length
\n" ); document.write( "\"L=w%2B8\"
\n" ); document.write( "\"wL=28=w%28w%2B8%29\"
\n" ); document.write( "\"w%5E2%2B8w-28=0\"---------Not factorable. Use the general solution to a quadratic equation to find w.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"w=%28-8%2Bsqrt%2864%2B4%2A28%29%29%2F2\"
\n" ); document.write( "\"w=%28-8%2Bsqrt%28176%29%29%2F2\"
\n" ); document.write( "\"w=%28-8%2Bsqrt%282%2A8%2A11%29%29%2F2\"
\n" ); document.write( "\"w=%28-8%2B4%2Asqrt%2811%29%29%2F2\"
\n" ); document.write( "\"highlight%28w=-4%2B2sqrt%2811%29%29\"-------and use this yourself to find L according to \"L=w%2B8\".
