\n" ); document.write( "Minus a -4/d is the same as adding it.

\n" ); document.write( "...
\n" ); document.write( "You can factor a 'd' from the numerator and denominator of the first part:
\n" ); document.write( "\"+%0D%0A%28d%28d%2B3%29%2Fd%28d-2%29%29%2B%284%2Fd%29%0D%0A\"
\n" ); document.write( "...
\n" ); document.write( "Then you can 'cancel' d/d because it is just 1.

\n" ); document.write( "Solving any faction, we create a common denominator, which in this case would be:
\n" ); document.write( "\"%0D%0Ad%2A%28d-2%29%0D%0A\"

\n" ); document.write( "...
\n" ); document.write( "Now we simply combine the fractions:

\n" ); document.write( "...
\n" ); document.write( "Can we factor the quadratic in the numerator?
\n" ); document.write( "Well, the factors of 8 are 1 * 8 and 2 * 4. We know they are opposite sign because we have -8. And we need them to total 7, which we can do with +8 and -1.
\n" ); document.write( "\"%0D%0A%28%28d+-+1%29%28d+%2B+8%29%29+%2F+d%28d-2%29%0D%0A\"
