\"%28x%5E2+-+3x+-+40%29%2F%28x+%2B+5%29\"
\n" ); document.write( "What do I multiply \"x+%2B+5\" by to get \"x%5E2+-+3x+-+40\"?
\n" ); document.write( "My first try is \"x\"
\n" ); document.write( "\"x%2A%28x+%2B+5%29+=+x%5E2+%2B+5x\"
\n" ); document.write( "subtract this from \"x%5E2+-+3x+-+40\", I get
\n" ); document.write( "\"-8x+-+40\"
\n" ); document.write( "Now what do I add to \"x\" to finish the division?
\n" ); document.write( "I'll try \"-8\"
\n" ); document.write( "\"-8%2A%28x+%2B+5%29+=+-8x+-+40\"
\n" ); document.write( "I'll subtract this from \"-8x+-+40\"
\n" ); document.write( "I get \"0\", so the division is finished with no remainder
\n" ); document.write( "The answer is \"x+-+8\"
\n" ); document.write( "To prove it:
\n" ); document.write( "\"%28x+%2B+5%29%2A%28x+-+8%29+=+x%5E2+-+3x+-+40\"
\n" ); document.write( "OK
\n" ); document.write( "
\n" );
