\"20z%5E5-95z%5E4%2B60z%5E3=z%5E3%2820z%5E2-95z%2B60%29\"
\n" ); document.write( "____________________=\"5z%5E3%284z%5E2-19z%2B60%29\"\r
\n" ); document.write( "\n" ); document.write( "Since we have produced \"4z%5E2-19z%2B60\", read my lesson entitled,\"Factoring trinomials: SHORTCUT!!!\" then go back to this page!\r
\n" ); document.write( "\n" ); document.write( "By the quadratic formula,\r
\n" ); document.write( "\n" ); document.write( "\"z=%2819%2B-sqrt%2819%5E2-4%2A4%2A60%29%29%2F%282%2A4%29\"
\n" ); document.write( "\"z=%2819%2B-sqrt%28361-960%29%29%2F%288%29\"\r
\n" ); document.write( "\n" ); document.write( "If you continue, z will be imaginary because of this part: \"sqrt%28361-960%29=sqrt%28-599%29\"\r
\n" ); document.write( "\n" ); document.write( "Therefore, this cannot be factored further.
\n" ); document.write( "So,\r
