\"4Z%5E3+-+18Z%5E2+-+10Z\"
\n" ); document.write( "= \"2Z%282Z%5E2+-+9Z+-+5%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So we have to factorise \"2Z%5E2+-+9Z+-+5\".\r

\n" ); document.write( "\n" ); document.write( "1. 2 x (-5) = -10
\n" ); document.write( "2. 1 x (-10) = -10 and -9 = 1 + (-10)
\n" ); document.write( "3. Given expression: \"2Z%282Z%5E2+%2B+Z+-+10Z+-+5%29\".
\n" ); document.write( "4. Taking common terms in brackets: \"2Z%28Z%282Z+%2B+1%29+-+5%282Z+%2B+1%29%29\".
\n" ); document.write( "5. Re-writing the expression we get the factors: \"2Z%282Z+%2B+1%29%282Z+-+5%29\".
\n" ); document.write( "
\n" );
